Something I think should exist that doesn't

UNIX magnetic poetry tiles. Really. I was talking to a coworker about UNIX commands, and she said, "What I could really use is something visual, that I could use to see exactly where the commands are and where the user-entered text is." So that got me to thinking - are there UNIX magnetic poetry kits? After a quick Google search, I came up empty, but for all I know such a thing does exist. If anyone out there could point me in the direction of such a thing, I'd appreciate it. Otherwise, I just might be forced to go out and create it myself...
