Friends and family keep asking in increasingly desperate tones what DS wants. Problem is, he doesn't want anything! His main present is going to be a Kindle, so I've said 'Amazon voucher' but people want to give a 'thing' and I can't think of anything! He's past the age for toys, already has loads of nerf guns, and friends/family don't want to give PS3 games which is about the only thing he actually wants.
Any ideas for some cool stuff?
