The Torgoen T01 sports a slide rule bezel. These aviator-style watches are like a poor man's Breitling, with battery-powered Swiss movements assembled into their housings in China. I've had mine for over six years, and I love it. The hands and numerals are large with phosphorescence that remains strong throughout the night. There's also a separate hand that reads in 24-hour time and which can be set to another time zone -- handy if you conduct overseas business.

I agree. I'm not sure it's even hill climbing in a follow-the-gradient sense, since a gradient is never computed. It's more of an optimized random walk. The overall performance would surely improve if a true, Holland-inspired GA involving both mutation and crossover on a large population were employed.

Another concern is the size of the polygons. If they are allowed to increase in complexity (i.e. by adding vertices), it's uncertain what the program really demonstrates. It'd be like starting with an amoeba and producing a chimpanzie by adding codons to its genome one-by-one and rewarding matches to the known chimpanzie DNA sequence. I'd have been more impressed if the "genotype" had been constrained to 250 triangles, say, and not allowed to increase in complexity along the way.

One feature of this demonstration does stand out as inspired, however: the use of semitransparency in the polygons. A couple of the intermediate renditions have a Cubist flavor to them in the style of Picasso or Gris. This I find to be more intriguing than the final result!
