Carnegie Mellon University, same thing. You really want to give computer geeks computers? Some programming exams are also given on apples booted into a special exam mode, but almost all have at least some written portion.

Nah, tweels are brilliant. you get more surface area (like a pneumatic tire if you have a stiff tweel, or more like a track with more flexible ones), but with the single point of rotation and simple mechanism of a wheel. yes, stuff gets in them, just like a regular wheel on a car, but it falls out nicely and doesn't weigh too much. expect to see more of them soon. also, scarab has regular wheels as well - they also went to hawaii. (and yes, ive seen the tweels up close, in person, on scarab)
