What is the chalkboard software that some mathematics and programming folks use on YouTube or when streaming?

It's actually not software at all. They use a glass surface between themselves and the camera with lights piped in the edges of the glass. They then use fluerescent markers to get the bright text effect.

Mirror the video image (or learn to write backwards) and viola.

There are some other ones where the presenter isn't on screen but it's the same software (or looks identical in writing style)
