Request for Geek Gift Ideas For Feature

I'd like to run a feature in the next few days about cool Geek Christmas present ideas. Don't just say a huge hard drives for MP3s (Thats first on my list already *grin*). Ideally candidates would be orderable online, but at least have URLs to descriptions and pictures. I intend to collect the most interesting ones and run a feature on them in the next few days. Email Me with the 'Slashdot Geek Gifts' in the subject and I'll post the results hopefully by friday.
