It’s two pieces of aluminum overlapping each other that have been lifted up to lean against each other. The cross bar shows two pieces overlapping below. Sorry, but this one was really obvious…

thanks luke and all those who saw it before. the bottom cross section has another piece underneath it. the top was placed like that, might have been tacked but i doubt it.

tsk tsk tsk tsk Its NOT VERY Hard Look at the other one thats strapped down…cant you see its overlapped?? Duuuuuh All we have to do is just unscrew those nails holding them down try to bend both of them the oposite dirrection and then when there good enough let go and they slam together creating what you see now

REMEMBER Illusions are simpiliar then you think!

What optical illusion are they talking about.
The lower portion has two overlapping pieces whereas the top portion they didn’t overlap and they just screwed them together.

The bent rhombus idea makes the most sense.

quite good explanation from Chain(#42) yet one certain factor affects the theory(an aluminum sheet from parallelogram to rectangular shape) w/c is deformation on its corners!if the cutting pattern is done precisely wherein the slant width of the parallelogram is almost vertical then fabricating this cut piece into its final form a rectangular shape will have a negligible deformation!you can check me out if you want the visualisation of the cut out piece.(autocad program)

It’s called welding. ^_^

ohhhhhkay… we have metal of all kinds, tooled and died into technological marvels like internal combustion engines, spacecraft, automatic weapons, or precision clockwork, and you all are marveling at a piece of aluminum with overlapping bars. arguably not an easy task but hardly worth any disbelief, i should think.

Following on the idea that Chain(42) gave I think i also have a possible answer: Imagine a flat but elliptical shape of aluminium sheet. Now take the shape in question and “elliptically” apply is to the elliptical sheet of aluminium (i.e. the long sides of the sheet in question was the short sides of the elliptical sheet of aluminium). With a little bit of tapping on the short sides of the elliptical sheet, you can bend them to become straight but ofcourse the inside bars would them overlap, which is exactly what we want! The longer edges of the elliptical sheet was simply cut off straight to form the short sides of the sheet in question!! :)

To anyone who has said ‘Photoshop’. Do the world a favour and stop breathing. This is an actual physical exhibit. Having seen it myself in Wanaka I think that Chain (no. 42) has offered the only sensible solution in relation to the actual problem, which I have to say isn’t clearly defined on this page.
