While in McNear's enjoying a couple of pints of Moylan's Irish Red, I finished a simple Python script to generate a Code 39 barcode using xhtml and css (I also tried with SVG graphics, yesterday, but then found out my iPod firmware 1.1.4 doesn't support it). Took the resulting barcode back across the street to the gym, and it wouldn't scan. Did some googling when I got home, and while a bunch of physics geeks say it's impossible for a laser to read a barcode off a computer screen, a number of people too ignorant to understand this have gotten it to work. Guess I'll have to get my own laser scanner and figure it out.
