Found this fun polygeek test through Karen's blog. ^_^ (Edit: Whoops! If all you see is a picture and a white block, try highlighting the block to read the text!)
You are 30% geek
You are a geek liaison, which means you go both ways. You can hang out with normal people or you can hang out with geeks which means you often have geeks as friends and/or have a job where you have to mediate between geeks and normal people. This is an important role and one of which you should be proud. In fact, you can make a good deal of money as a translator.
Normal: Tell our geek we need him to work this weekend.
You [to Geek]: We need more than that, Scotty. You'll have to stay until you can squeeze more outta them engines!
Geek [to You]: I'm givin' her all she's got, Captain, but we need more dilithium crystals!
You [to Normal]: He wants to know if he gets overtime.
(Edit 2: Here's another test that I took. It seems pretty accurate in a literal sense as well--re: I am yellow.)
YELLOW
You are very perceptive and smart. You are clear and to the point and have a great sense of humor. You are always learning and searching for understanding.
