ADVERTISE AT BOING BOING!
The second item of note from my rummage on Shapeways this morning is Wahtah's Sierpinski tetrahedron, a fractal pyramid with 499,994 faces.

Oops. Shoulda flagged, huh?
That really is a lovely little thing. It’s grand, living in the future.
This : )
I saw one of these back in the 90′s. Then the acid wore off.
It wears off?
Not really. 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.
BTW, the goats were de-bleated. Wouldn’t want to have them making noise while you were stopping their hearts by staring at them.
so they say
Funny, it only looks like 4096 faces to me:
Shapeways charges by the cubic centimeter.
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!
You can think of the Sierpinski tetrahedron as the graph of the exclusive or function. If you plot a point at each point (x,y,z) where x= y XOR z, you get this.
This may be the most efficient dust-collector ever, but I still want one.
The Sierpinski gasket makes me want to cry.
