Eggbot Printing

After reading about the Eggbot at Evil Mad Science and seeing it in action at the East Bay Mini-Maker Faire I was hooked and ordered one.  I've had great success printing on eggs and ornaments.  The trickiest part of the whole process is developing a .svg vector art file that prints good results.  Because it uses an actual pen (a fine tip sharpie), printing must be done using lines instead of the usual dot matrix method.  That means filing in regions of solid color must be done using zig-zaging and/or multiple vectors.
