As an avid reader of Hacker News (news.ycombinator.com) with a keen eye for articles about time and clocks, I naturally came across this excellent post by Doug McCune called Visualizing Time with the Infinity Hour Chart.
In Doug's post, he talks about using this technique to represent data related to a particular time of day. I immediately though "Man, that would make a cool watchface..."
Fast-forward a few hours when I logged onto the inPulse developer forum (http://forum.getinPulse.com). Trammell Hudson, the hacker behind the Magic Lantern firmware for Canon DSLRs, is in the midst of his own 30 Days of Watchapps. It turns out he read my mind and created an inPulse version of the Infinity Clock.
