| There appears to be a gradient in the "proof" picture. If I feel like firing up my machine with photoshop on it, I can verify this...but it seems a little sketchy. |

Regarding the one with the elephant legs...they draw the legs right, but put the feet in "space" that doesn't even exist, it appears. So the elephant still has four legs, but he has no feet, as they've all been severed and are sitting directly in front of each of his legs. |

I guess the analytical side of my brain makes that one not so difficult. When you rearrange the pieces, the slope of the hypotenuse changes for the second triangle. The pieces are, in fact, the same size, but when you rearrange them, the second one has more area to cover.
If you look at the size of the "white space" above the hypotenuse as the line moves from left to right, you'll see that it varies between the top and the bottom triangle. Long story short, the bottom triangle is trying to cover more area and comes up short by a square.
There may also be a very very slight bend in the lines to assist. |

hmm, ok I did this in Adobe Photoshop, and it is indeed the same color. I drew all over the board. I still don't believe it even though I did it myself. I guess it has something to do with the shadow of that cylinder. |

Yep me too, I don't believe it either, but I will take your word for it!  |

| Well it certainly has to do with the cylinder's shadow...but there's more at play. While it contains the same color(s), it's not a consistent color throughout. There's shading involved, although slight. A variation of 4-5 on an RGB level can make a slight, but significant difference. Regardless, it's still funky. |
