How's this for a cool tiny little radio control plane? It weighs in at only 4 grams and is fully remote control. Now you can fly planes when the weather is crap too - in your lounge instead of out in the rain. I wouldn't want to take this outside - one sneeze and it's gone, but it looks great fun. Full details can be found here and a little video showing how it works is here.
Another possible entry on your christmas list Steve?
