The beer garden has been quiet for a little while, so I thought I would start something new.

Does anyone enjoy optical illusions? Here is one that's been around for a while, but that I find to be quite amazing. Even when I prove it to myself I still can't believe it:

I could never figure out the one with the triangles. Anyone know how that one worked?

It works because the hypotenuse of the large triangle is not actually straight, if you calculate the slopes of the red and greed oones, one is .4 and the other is like .42 or something. This is why...

Who's the smart one now Derek?! :wink:
