I've always liked building things...I played with Legos a lot when I was a kid, but they really annoyed me because I would run out of pieces or not have the right size, and it's hard to cut up Legos. Had to improvise with things like erasers and duct tape =P
But now, I have POWER TOOLS!!! *maniacal cackling*
I'm into programming too. I use Java more than C though, so I have to switch gears now. Also, most of the nerdy/math/science people were in robotics, so I knew a lot of them. I used to be primarily a mather
here but I think that now robotics has the most priority in my life. (...my grades aren't so great around February

)
I almost decided not to join because of the time commitment, but I did and I ended up really happy with it.
That is, after the freshman initiation rites of filing. *ominous drum roll*
