Ardesia enables you to make colored free-hand annotations on your screen and record it.
This is especially useful when making presentations, to highlight things or point out things of interest.
Ardesia is XInput-Aware, so if you have a mouse, a graphic tablet, a touch screen or a whiteboard, you can draw lines with different strength, select color, erase things and draw arrows. You can free-hand draw geometrical shapes using the shape recognizer, insert text with the keyboard and highlight screen areas. You can draw upon the desktop or select an image as background.
