Since I've scratched the coding itch, it's only gotten worse. Sarah is taking part in the Hartley Ability Cycle Challenge in November, which is a fundraising activity. I knocked up a webpage for keeping track of how much money they've raised.
It took a bit of lateral thinking to get JpGraph to produce the goods, but it wasn't that difficult in the end. JpGraph is truly awesome stuff. It's just a shame it's got a dodgey dual license that precludes its inclusion (well a more current version) in Debian.
