Think Geek has a great tie on the site. It as a pattern in the weave that’s binary, The ASCII code of the binary comes out as “Ties Suck”. Great for when you hate ties and want to be smug aroung the office.
On the topic of binary they have a binary watch that you can show them when someone asks for the time.
The Nasa gel blue led ant farm isn’t to shabby either. It use a gel nutrient for space experiments on ants.
Anybody else have some great geeky devices you know about?
