TapedUp, Tinkerer, and Rumpled are based on the template I used for some of novelty fonts -- fonts made of wrenches and bolts, hammers, or paper clips.

TapedUp can be thought of as a font made from masking tape, and Rumpled is the same design but the tape pieces are wavy. Tinkerer is the same design but with elements that resemble what might happen if one constructed letters from TinkerToys.
