Brushkkake

Set up a canvas and let your chat users paint something using a simple command:

!x y [color] [brush]

• Color: any HTML color, defaults to black.
• Brush: from 1 to 5, defaults to 4.
  Examples:

• !5 10 #03de31  1
• !4 3  (black )

Pixel Art mode: only fixed-sized squares will be painted. (see advanced options)
