Called Descartes, this little thing can roll around in total silence, follow people, hunt down evil light sources, run away from 'threats' and draw pictures as seen in the nifty movies. It's also got a speaker, temperature sensors, 'bumper' sensors, and a slew of gadgets to make Sojourner jealous. It's fully programmable via PBASIC to do anything you want, and what's more, it's relatively cheap. The evil possibilities of this device fill my heart with glee ..."
