Whoever says Dorkbot consists solely of computer-science freaks and geeks who can mentally compute the velocity of their own pee is a big fat liar. Believe it or not, they also have artistic talents as you will see tonight at Dorkbot #4.

They?

• Weird Science Salon Founder and mad professor emeritus William J. Beaty demonstrates his Crooke's cathode ray tube, and knowing Bill, other possible surprises as well.
• SolarRichard will bring a working model of the LEDs he proposes to put on the Tacoma Narrows bridge, and will explain how the solar "Ecotricity" will power them.

There will also be an open dork after the presentations where anyone can take the floor for about 10 minutes to dork out on science stuff.
