Earlier this year I was looking for one of those clean/dirty magnets for the dishwasher -- and I found a whole new category of things to look at... We ended up getting this to go on our aging dishwasher... We were very happy with the quality of the print and magnet, you can also order a film for non-metallic surfaces.

But this thread made me think about this one, I decided I would sort of be creeped out by these nice kitchen partners...
