ITC Tremor is the work of British designer Alan Dempsey. You might think that it looks like the letters are in a seismically lively geological zone, but Dempsey had other kinds of motion in mind. Most of the faces I design come from trace 'work-outs' for advertising products. In the case of Tremor, it was to reflect a lively teenager," says Dempsey. The result is ITC Tremor, a cartoony slab serif typeface with irregular angles, straight-edged curves, and lines surrounding each character, making them look like they are jittery.
