Creepy Bug

This creature was crawling around at work this morning. I don't know what he is, but I'm hoping he stays away from my feet!

UPDATE: It appears, after doing some research online, that this is a 'camel spider'. They have a very bad reputation for being really dangerous, but much of what is said about them is not correct. They can give a painful bite, but they are not venomous. This particular one was aggressive when I tried to shoo it away. Instead of retreating, as most bugs would, it turned towards me and raised its large front legs (or whatever those are) in a threatening manner. I got the message and backed away. After that, though, it seemed content enough to be photographed.
