Very rough gears. Don't try this at home.

u/tomxor

With an arrow function there is enough space for some tapered gears :) g=(a,b,n,r)=>{ then i-=d,i+.05)
u/tomxor

Arrow function seems to need a space after the } though !
u/somebody

c.width+=0 and replacing d with .1 directly saves two bytes. might be able to improve the tapering or something
