The Lightboard is a glass chalkboard pumped full of light. It's for recording video lecture topics. You face toward your viewers, and your writing glows in front of you.

I'm not writing backwards! The board is videotaped in mirror reflection.

I developed the Lightboard to be able to record attractive online lectures, easily. In technical subjects equations and sketches are important and I use my hands a lot as I write and talk. This process is direct-to-disk, so you can do it yourself with little or no post-production.
