Couple of weeks ago, I got the idea of mugs with puzzles/riddles on them, to set out for guests. Looked around online, didn't find anything like that, so figured I'd make something on a design-it-yourself site.
Then I thought others might be interested, so I
made a whole bunch here.
Think this would interest people? (Most of you aren't into puzzles much, but hey, use your imaginations. >:) )
Any ideas/suggestions? I could slap the same thing on shirts/bumper stickers/whatever, but it's not worth the effort if it's just going to gather virtual dust.
