Bent Lines Illusion Canvas

I had a bit of spare time on my hands at lunch and created a little JavaScript application of the Bent Lines Illusion I blogged about earlier which was a re-post of this Richard Wiseman blog post.

The application allows you to change the orientation of the black diamonds by clicking on them which makes the perfect grid of squares look really weird.

The application can be played with HERE

Try changing a straight line of them right through the middle to start off with to see how the effect works. Remember that the squares are all equal, straight edged and perfectly aligned!

I have tested it in FireFox 3, Google Chrome, Apple Safari 4, Internet Explorer 6, 7 and 8 and it seems to work fine in all of them except IE6 in which it works but incredibly slowly. Please give any bugs, comments or suggestions as comments to this post.
