Some other Name sites have posted some great geeky names recently! These sites are worth a read:
Baby Name Pondering profiles names from the T.V. show Sliders.
Mer de Noms also discusses the Dwarves of the Hobbit.
Bewitching Names profiles two great astronomical names: Vega and Io.
My Name Is Pabst gives us Rand, from Robert Jordan's Wheel of Time series.
Oh, and check out this post over at Baby Name Pondering. I'm a little dubious on using Pixel for a person, but it's adorable on that cat!
