Turbo colormap. Use localStorage["tcm"] (256 elements array)

u/katkip

Add localStorage.tcm = T; for (i in T) x.fillStyle = T[i], x.fillRect(i*5,0,5,2e3)

Explain how "dwitternet rules" text is generated: t=x=>"abcdefghijklmnopqrstuvwxyz "[x];Q=v=>{s='',q=0;for(i=0;i<4;i++)q+=S(i*v+q*q)*v+i,s+=t(Math.round(S(v+i*q+v*v)*13+13));return s};throw Q(869453)+Q(347181)+Q(199311)+Q(1271309)

u/jellyedwards

It looks like Q generates random 4 char sequences given a seed and you've found the seeds that give you dwit, tern, et r, ules? A bit like how the Feynman point works, you can find whatever sequence you like eventually in an infinite random sequence.
