Jittery Compass and Imperfect Ruler

Including perfectly drawn circles using a compass or hard edged ruled lines in an otherwise hand rendered image is never a good combination. The Jittery Compass and Imperfect Ruler solves this problem.

The ruler is simple. It's a basic hollow square shape, meaning that it has 8 sides, each of which is damaged with a series of random nicks and kinks. Variety is created by using different parts of the ruler to create various parts of the drawing.

The compass is more complex. To make the jitters as you hand turn it, requires setting a small gauge on the handle. This controls the amount of tiny spasms created by a random micro vibrator, which are delivered down the shaft to the pencil end.
