Whirligigs for the New Year

Friday, December 30th, 2005

Some people begin the new year by pledging to lose weight or quit smoking. My usual pattern is to try to find two or three new obsessions each year. Perhaps it’s more accurate to say that these obsessions find me! This last year, those obsessions included digital photography, photo mosaics and logic puzzles. After 20 […]

Krypto Kakuros

Thursday, December 29th, 2005

I’ve developed a new kind of puzzle which I’m calling a Krypto Kakuro. They combine elements of crossword puzzles, sudoku and cryptograms (or cryptarithms to be precise).

Friday, December 2nd, 2005

My phyllotaxy poster has been showing up in some unusual places, other than the sides of refrigerators. Not too long ago, it showed up as part of this amusing keynote presentation by Dick Hardt, for the O’Reilly Open Source conference. Dick was talking about new web technologies, and used an early image of the poster […]

Making Music with ABC Plus

Friday, December 2nd, 2005

A few days ago I went hunting for free music notation software. Once again I was struck by the bewildering array of music software out there, clamoring for your attention. I found at least a hundred notation packages alone. I think the reason for this is that a lot of musicians are programmers, and it […]
