Ok, we both know this isn’t a real 4D Cube (also known as Hypercube). Never the less, this animation really blew me when I first glazed my eyes on it. If you are interested more in mathematics behind 4D spaces, be sure to browse Wikipedia. In the meantime, enjoy!

4D Hypercube Optical Illusion

  • marry

    boring I can make that

  • jolovesthisanimation

    That is so wicked!!!!!!!!!!!!!

  • mg


  • Connor

    That’s not even 4D, what a gay image

  • niki

    it’s just a box inside a box… *stares blankly*

  • zippy the turtle

    click on the link for the animation! its not just a box in a box people learn to READ

  • sbredflag

    Pretty cool!

    • CoaCo

      Its just a 4D version of a 2D square ore 3D cube rotating

  • NIC


  • kristen

    ok…what you do is READ THE STATMENT OBVE THE PIC click on the link AND WATCH THE ANIMATION omg DUH

  • shado.za

    oooooohh!! i always wondered what made hypercubes special!

  • rae

    maybe I’m missing something…(yes I did see the animated version), but couldn’t this object be made in RL with some sort of stretchy/gummy material?

  • Rachael

    That’s almost hypnotizing. Aren’t those called tesseracts?(don’t know how it’s spelled)

    • Josiah

      I think that this is awesome
      (and you spelled it right.

  • Kim

    I dont see the animation, what is it supposed to do?

  • Kim

    nevermind :p, cool stuff

  • Me


  • Bob

    It is not possible to visualize a 4D object with 3D imaging no matter how fancy the animation. The visual concepts are beyond the abilities of the human brain. All we can visualize is the shadow of a hypercube presented as a 3D object just as a square is a 2D representation of a cube.

    it is however a very pretty animation

  • Adithien

    If you’re interested in the fourth dimension, might I recommend “And He Built a Crooked House” by Robert A. Heinlein. Very cool short story if you’re geeky like me

  • alana

    if u see the animation, it almost puts you to sleep. not of boredom, just cuz its relaxing and hypnotizing

  • me

    zomg thats amazing!

  • DUDE!

    This is so wicked!!!!
    you have to go to the link above it!!!!

    what does this cube represent? 4D. BUT can it be applied to anything? this doesnt explain 4D because it’s only a cube. but my question is: can anything be in 4D? or does it only have to be a cube? and isnt 4D time?

  • Cool

    Each edge of the cube is the same length, you cant reallly tell but if you think about it they would have to be, the cube inside is smaller because the cube could not only move up, down, left, right, in and out it can also move to seem smaller or bigger (shrink or expand). And to answer your question no it doesnt have to be a cube, yes 4D is time and this is basicly an example of 4D it is not what 4D IS but just an animation made to aid you in understanding it.

    Thats my opinion, pretty good stuff.

  • loser

    just a box..inside a box…kinda boring..*stares* *not interested*

    yes Rachel, it is…

  • idontlikeanything

    That is not even an animation, wrong category

    LOOK AT THE ANIMATION, DANGIT! I don’t mean to be rude, but really, people…

    *staring blankly* a box..wow..this fails to amaze me..

  • Anonymous

    u dumbasses need to click the link to the animation… dumbass

  • jrgruntly

    LOOK AT THE ANIMATION STUPID!!!!!!!!!! omg u ppl have tumors in ur brain

  • Anonymous

    i used to have this mind toy that was put together exactly like that. using tubes and elastic string. or something similar O.o fuuuuun

  • Anonymous

    am i suposed to be amazed

  • Sandoras

    Makes a lot of sense after taking it and watching it frame-by-frame in my cheap photoshop program…Still, excellent illusion

  • The AMBINATOR _u m ok,BORING!!!!!!

    That is not an illusion!! I can make that out of magnetix!!!!!!!!!!
    All the people that think this is an illusion are dumbasses! The rest of’em are on my side=^^=


    Ok, Anyone who thinks this is NOT a illusion is WRONG.

  • Cory

    cool it makes me think of the mist games for some reason!

  • Politikally Paranoid

    Tat iz so kewl. I wanna know how dat happened yo!

  • Griffin

    i dont know about anyone else, but all i see is just a stupid picture of a shape that anyone can make out of magnetix sticks!!

  • www.yourgay.co.u-gay

    that hyperpube sux!
    geddit! hyperpube! lol

    The picture did nothing. I clicked on “animation” and found an advertise window. Is this why we were asked to click on -animation- link? Please find other ways to advertise.

  • Anonymous

    Yes, this cube IS really called a tessaract, and yes, it IS really four dimensional. Look it UP!
    And don’t click on the picture, click on the link. Pay attention!

    • Laura

      Yes, I thought it was a tesseract. The fourth dimension is time.

  • Anonymous

    Alothough, no, I’m pretty sure it’s not actually a real illusion.

  • Schunki

    it IS a 4d Hypercube… there are also 5D, 6D … and so on

  • Anonymous

    well if it is an advertisement then it is a great way to do it.

  • chris flucture

    its amazing,ihave never seen this ever before

  • Nigel

    Why can’t people read The Time Machine by H.G. Wells? The fourth dimension is time, all objects are in the fourth dimension. Time, duration, call it what you will, have you ever seen a cube in only 3d? An instantaneous cube?

  • Anonymous

    dats awsome!!!!!!!!!!!!!!!!!!!!!

  • Coolio

    i think of marshmallows when i c this…..maybe im just hungry.

  • Amber

    Nigel – You’re not really getting dimensions. Yes, the fourth dimension we, the common public, experience is time, but for mathematicians, who know there’s more, it would be bad practise to label time as the “4th” dimension when there are more spacial dimensions after the 3rd.

  • Silver

    I must get one of these in RL. I will play with it for hours!

  • steve

    its from that movie called “The Flatlands”

    • Allison

      haha i watched that in geometry class.

  • Noone

    I luv this

  • javacuzi

    thats too cool

  • Guido de Mossimo

    it kind of folds into itself…….. coolio tho

  • derek

    it looks kool, but i think its being turned round and round.

    • http://www.bing.com/ Sparky

      You’ve got to be kidding me-it’s so transparnetly clear now!

  • SefronZ

    the 4° dimension is the time :)
    the 5° dimension is the light :)
    and maybe there is 6 more dimensions

    • anonamus

      those rnt dementions stupid all the dimentions are of a phyical mesurement length width highth time isnt a dimention and neither is light or else the original mario would be 4d which its not

    Mathematically four-dimensional space is simply a space with four spatial dimensions, that is a space that needs four parameters to specify a point in it. For example a general point might have position vector a, equal to

    \mathbf{a} = \begin{pmatrix} a_1 \\ a_2 \\ a_3 \\ a_4 \end{pmatrix}.

    This can be written in terms of the four standard basis vectors (e1, e2, e3, e4), given by

    \mathbf{e}_1 = \begin{pmatrix} 1 \\ 0 \\ 0 \\ 0 \end{pmatrix}; \mathbf{e}_2 = \begin{pmatrix} 0 \\ 1 \\ 0 \\ 0 \end{pmatrix}; \mathbf{e}_3 = \begin{pmatrix} 0 \\ 0 \\ 1 \\ 0 \end{pmatrix}; \mathbf{e}_4 = \begin{pmatrix} 0 \\ 0 \\ 0 \\ 1 \end{pmatrix},

    so the general vector a is

    \mathbf{a} = a_1\mathbf{e}_1 + a_2\mathbf{e}_2 + a_3\mathbf{e}_3 + a_4\mathbf{e}_4.

    Vectors add, subtract and scale as in three dimensions. The dot product also generalizes to four dimensions, like so:

    \mathbf{a} \cdot \mathbf{b} = a_1 b_1 + a_2 b_2 + a_3 b_3 + a_4 b_4.

    It can be used to calculate the norm or length of a vector,

    \left| \mathbf{a} \right| = \sqrt{\mathbf{a} \cdot \mathbf{a} } = \sqrt{{a_1}^2 + {a_2}^2 + {a_3}^2 + {a_4}^2},

    and calculate or define the angle between two vectors as

    \theta = \arccos{\frac{\mathbf{a} \cdot \mathbf{b}}{\left|\mathbf{a}\right| \left|\mathbf{b}\right|}}.

    The cross product is not defined in four dimensions. Instead the exterior product is used for some applications, and is defined as follows

    \mathbf{a} \wedge \mathbf{b} = (a_1b_2 – a_2b_1)\mathbf{e}_{12} + (a_1b_3 – a_3b_1)\mathbf{e}_{13} + (a_1b_4 – a_4b_1)\mathbf{e}_{14} + (a_2b_3 – a_3b_2)\mathbf{e}_{23} + (a_2b_4 – a_4b_2)\mathbf{e}_{24} + (a_3b_4 – a_4b_3)\mathbf{e}_{34}.

    This is bivector valued, with bivectors in four dimensions forming a six-dimensional linear space with basis (e12, e13, e14, e23, e24, e34). They can be used to generate rotations in four dimensions.

    thats the math behind it! =]

    That’s so cool! It kinda makes a cube in the middle :P

  • Trent

    Never the less, this animation really blew me when I first ….
    Am I the only one who caught this??

  • unknown

    no i got it the out gets in and then the in gets out

  • toni

    MATH 4D is real, when it comes to “math” concepts only. Animating it is stupid as the real world is 3D, you only need to specify x, y, z, to get the point you want.

    any nD space is OK in math, but not in reality, the above image is silly, it’s just a 3D object anyway.

  • Kam

    Imagine looking at a video of a normal 3D cube rotating. Because of perspective the side away from you looks smaller. As the cube rotates it appears that different sides are getting smaller or larger.

    The animation above shows the same effect for a 4D cube. The perspective projection of the 4 dimensional cube onto a 2D surface means different edges will appear shorter or longer. The hypercube is not stretching. In four dimensions all of its edges are the same length and all the angles are 90 degrees. But as it rotates, the perspective projection makes it appear that parts are shrinking and that one cube is moving inside the other.


    all lies! a hypercube is real I watched a documentary about 4d things
