Hey y'all just thought I'd start a thread for xmas gift ideas for geeks and non-geeks alike. My dad & my brother both appreciate the geekier/techy side of life so am looking for good gift ideas. My mum & my sister not so much but I am getting a Kindle for my sister at least

Last year my shopping list included meteorites, trinitite, rare-earth magnet toys and other such things, all of which were well received. Want to go a bit different this year. Also have a very smart 6 year old boy to buy for too

Are there any good small robots available these days? Am thinking something along the lines of Robosapien, as those were a load of fun.

Any other ideas? What are you guys getting for the geeks in your lives?
