Writing code since 1979
I have been a professional software engineer for over 10 years. I have written many kinds of software, but my particular strengths are interactive graphics applications, compilers and interpreters, and algorithms.

I also enjoy writing, woodworking, and home improvement. Also this.

Somebody made a thing they're calling a
propellor clock; this is a single vertical row of LEDs mounted on a motor, with circuitry that "draws" the clock in the air by changing the pattern on the LEDs as the motor spins the whole assembly. I remember thinking of this when I was about 10 years old (a little over - gulp! - 20 years ago), but at the time I didn't have the mechanical know-how to actually build it. I had completely forgotten about it until I saw that link; I wonder if I still have that page of notes somewhere?
