This is a well known variation of bent lines illusion. There are hundreds of them, but this may as well be a representative specimen. No matter how much of them I see, I still haven’t managed to solve the mystery behind them. As we see, the little black and white squares give the impression of a line that seems to bend from center to outer rims of the background. Quite frankly I don’t understand how this effect works. If you examine the picture up from close, you can only confirm that all squares/background blocks are aligned perfectly, horizontally and vertically. Moreover, all of them are straight and parallel one to another. It’s like we have all the necessary ingredients, and still the result comes different than we expected. Anyone knows what is this effect called? I’d like to study it a little more… You can see the proof of parallelism’s inside this post.
On the site news, I updated Seemingly Bent category with new illusions and updated all the links inside with our new domain redirects. You should still test it, if everything works fine. Peter also mailed me an update concerning his Free Game offer from post below, and prolonged his exclusive offer to Mighty Illusions until Friday, 9th. Get those free games before the offer ends (value $40). Happy huntin’ :)
