My very first solution, also around 140 strokes, used trigonometry. I'm a different animal from Andrew, I think, and I prefer solutions that make some sense, rather than a magic formula, or unpacking a bizarre string :) Here's a speeded up version of my whittling! The first solution has ints on both indicies, uses .524 (which I think is a closer approximation of the hours to radians factor than .52), brackets around everthing - generally a mess. I was relatively quickly able to get rid of most of the bracketing, eventually got rid of one int, (then much later the other!), and trimmed the numbers to fit. I think the best bit of golfing was to change 5.5-4.7*cos($_*=.523) to $_*=.523,5.5-4.7*cos. It was one of those "I don't think this will work but I may as well try it" moments! Hurrah! There are quite a large range of numbers that produce the correct pattern, but only a few with the least number of decimals. I think this is fairly optimal. I'm going to assume(!!) that Andrew has tried and failed to better this.
