OK, so my employer is lending out raspberry pis for "cool" demo projects to
be completed in a couple of weeks. I was thinking of doing a Sudoku solver
in Plan 9. I have written working C code for a command line solver using
Knuth's exact cover / dancing links algorithm. Advice sought on how to
program the UI to look not totally shite. Or indeed, to exist at all. I
should say that I have yet to install Plan9 on the pi, so could be a big
ask. Any help, even abuse, will be accepted.
