Here and then I feel like having a burden of “responsibility”, where I remind myself it would be irresponsible if I didn’t al least provide occasional education, specially when there are so many young-ones among us, whose minds are still forming and thirsty for knowledge! Before I explain the science behind this interesting phenomenon called [...]

How many toads can you see in this photograph?

National Geographic is proud owner of some of the best photos in the world. Here and then a photo jumps out, containing an interesting effect which sometimes can be seen as optical illusion.

As you can imagine, it becomes harder and harder for me to find quality optical illusions, and continue posting them regularly.

Whoa! Not only did I miss the second hidden face in our previous illusion, but was shocked today when I saw how many of you made a comment to point it out to me. As of this moment “Undershirt Illusion” has passed 300 comments, and all of this in less than 24 hours. By the [...]

Concentrate on the red spot in the middle of the rectangle, and watch gray stripes disappear! This one is really cool, eventhough simmilar illusions have been posted in the past. Can you explain why this effect happens? I would really like to know why! P.S. Due to popular demand, Mac games are bout to be [...]
