This ingenious Javascript maze appeared on ldb's site, "thatgrrl.com/ASCII/maze.htm". Alas, as with so many supposedly useless things on the internet, thatgrrl.com has disappeared. She has moved her site to thatgrrl.ca but the ASCII maze is not there - indeed, there is no ASCII art there at all. I really hope that ldb doesn't mind that I have included the maze here:
Many thanks to the Internet Archive WaybackMachine for saving the maze!
