uncompressed: `x.stroke();onmousemove=r=(i,v,b,K)=>v?x.lineTo(v,b,c.width|=A=Math.atan2,L=_=>{r(i-1,v+99*C(K=S[i]??0),b+99*S(K));S[i]=K+A(M.y-b,M.x-v)-A(d-b,s-v)},i?L(L()):(s=v,d=b)):r(6,960,540,M=i)`

• red is shorter than any other color! :D
• u/firegodjr
Looks like a rose :D
• u/Agnes
For the record, `strokeStyle="tan"` is as short as red.
• u/magna
`R(k)` also seems to work
• u/zanella
You can replace `1.57` with `1.6`, and use this extra byte to use hex colors instead of `red`, like `#0f0`. ;)
• u/zanella
Or, if you want to keep it really precise, replace `*1.57` with `/.64`.
