If you plot a point at each point (x,y,z) where x= y XOR z, you get this. You can think of the Sierpinski tetrahedron as the graph of the exclusive or function.

If I'm not mistaken, the Sierpinski tetrahedron converges to zero volume. He should have made it more detailed, and he could have gotten it for free! Shapeways charges by the cubic centimeter.

You just kinda get used to it. And I took it in the 70's. And BTW, that whole story about thinking you can fly. Total horseshit. The story probably got started when the CIA shot one of their own in the head and then threw him out of a hotel window because he was about to spill the beans of them experimenting on random US citizens. Think I made this up? Read Ron Jonson's "Them!" And you though staring at goats was weird. Not really. You just kinda get used to it. And I took it in the 70′s.
