Here is a utility for drawing and testing your own puzzles. It was inspired by an email from Ian Hincks, who offered some code precisely to do this (Thanks!), but I decided to have a go at writing something myself.

Hold down Ctrl to paint white. Use the arrow keys to move the whole picture.

Oops! I don't seem to have got this to work for IE yet. I'll have to give it some more thought.
