    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)

u/DataMeta

This must be nearly the shortest dweet
u/Xen

nice find geb, check 2923 datameta, altho xem and others have done smaller ;)
u/katkip

Wow!
u/geb

better tag them from now on #Sierpinski
u/pavel

Basically the same thing but in 40: for(i=3e3,t*=99;i--;)x.fillText(1,t|i,t)
u/Xen

37 but not as good: for(t*=i=1e3;i--;)x.fillText(i,t|i,t)
