  • zensaiyuki: zensaiyuki: I found this trick for generating a 16 color palette: i*0x775511. i wonder if it can be made smaller in javascript.
  • iverjo: Neat. To begin with, you can replace 0x775511 with 7820561. Further, you can look into bit operations or modulo to truncate/slice the string

  • cantelope: If you set canvas.width to client.width, you can remove the bit that fixes the mouse position. This one only works at the default width (not fullscreen) because I had to hard-code the canvas width to make room for the fade effect. Nesting stroke inside beginPath saved 1 crucial byte. :)
