Algodoo

An orange box emits circles from the bottom of the box toward the top. A laser intercepts this stream of circles and measures its deviation from its predicted path. This then produces a variabe "scene.my.angvel0" which is printed to a box. It manages to be relatively accurate up to 3.5 rad/s.
However, it reads very far off when accelerating laterally, and slightly when accelerating vertically.
