An experimental spiral painting mode for RoboPaint

This module is a mode for RoboPaint, the software for drawing robots, and your friendly painting robot kit, the WaterColorBot!

This mode gives you the ability to pick any image and have it "painted" at a height, varying between 40% and 100% down, between the "up" position and the draw position, depending on the gray value at a given spiral position around the image. The image above was created using the Tombow dualbrush pen, but regular paint and variable width brushes work well too, as long as you don't have too much water and you can get your calibration just right.

Different images can be combined in one, like this faux CMYK color separation image. For this example, color separation is done in Photoshop by copying the Cyan, Magenta, Yellow and Black channels outinto individual gray images which are painted each with the apprioriate color.

It's exceedingly important that your paper stay flat for these prints, and as more ink/paint is added, the paper invariable warps. I highly recommend adding a small amount tape or slightly tacky removable glue to the bottom of your paper to ensure it stays as perfectly flat during the print as possible.
