I love Sierpinski Triangle - it is a simple construction, yet gives a lot of insights. For example, it can be constructed both top-down and bottom-up, showing the duality of nature. In the top-down case, you divide space into infinitesimal, while in bottom-up, you count to infinity, adding more and more bits to the triangle. Both figures are the same at infinity.

I'm not familiar with the bottom-up construction. The sierpinski triangle is the result of repeated linear transformations applied to a set (hutchinsons theorem). The cantor set is another example, as is the koch curve & the cayley representation of a free group on two generators. This all sounds freakishly advanced but is extremely easy and approachable even to non-math people.
Did /prague/ know that it's possible to type "Satori" in Colemak without moving the fingers from their default position? Forget fucking qwerty and learn Colemak!

>>7 Why don't you just rest your fingers on SATORI on a QWERTY like everybody else does?
Basically, this. S0 = {(0,0), (1/2,1), (1, 0)} T1 (x,y) = (1/4x, 1/4y) T2 (x,y) = (1/4x, 1/4y) + (1/2, 0) T3 (x,y) = (1/4x, 1/4y) + (1/4, 1/2) S 0 = S0 S n = T1 (S n - 1) U T2 (S n - 1) U T3 (S n - 1)
Where the U symbol means set union and the game means you lost it.
