AUSTIN, Texas--It's almost two in the morning and I'm standing in the middle of Austin's Sixth Street, hoping that I'm not going to get hit by a car.

On the other hand, I am hoping--as are 15 or so other people standing nearby--that one of the cars that keep rushing by will crush the tricked-out Roomba robot vacuum cleaner that Make Magazine associate editor Phillip Torrone and Eyebeam R&D fellow Limor Fried are sending back and forth across the street and through traffic.

This is Roomba Frogger, a modern, geek version of the famous 1981 video game "Frogger," in which players had to get a frog across a street without it getting crushed by a car or truck.
