Drawing with light and AxiDraw

The folks at myDesignLab made long exposure RGB LED drawings using AxiDraw, even going so far as to make multi layer three dimensional drawings.

Lindsay Wilson used a laser in a similar manner, first with long exposure photos, then with a UV laser and phosphorescent vinyl and then with a UV laser and cyanotype paper. The cyano print shown above is an example of his experiments drawing Lorentz attractor patterns.
