ON A SIDE NOTE...

My parents flipping love SuDoku, (my mum especially) and I am currently in possession of something like 50 SuDoku books that have been completed and I am trying to think of something to do with them... There must be something like at least 10,000 SuDoku puzzles here, and there HAS to be something i can do with them... I'd feel bad throwing them out, they seem so useful... in a completely useless way.

Any suggestions?
