Scriboard

Scriboard is an application that allows you to draw over your Desktop: over the Dock, windows, the menu bar, floating windows...
It is a useful tool when doing video-projection to quickly highlight some of the projected elements.
Scriboard has four markers with a customizable color each.

You can change on the fly the opacity and the thickness of each marker with keyboard shortcuts.
You can also put text labels on the screen, which are customizable, and moveable and editable at any time.
