We like the Orbit clock. By using circular hands, it emphasizes that time isn't just a linear progression of events — more of a big ball of wibbly-wobbly timey-wimey stuff, a point of view shared by our favorite Time Lord.
Technically called the Orbit-r, the clock is a sequel to Dave Keune's original Orbit clock, which used ellipses instead of circles for a more dramatic effect. We're fans of minimalism (not to mention timefaces that aren't so difficult to read), so we're going to cast our vote for the new version. Contact Keune if you want one.
