Solar-Power Your iPOD

I thought you iPOD addicts out there might want to build yourselves a solar iPOD charger so you can still listen tunes if there's a nuclear holocaust. Also good if you are just looking to save a penny or two on your electricity bill/reduce your burden on the power grid by some infitesimal quantity/listen to music in the backcountry. Or hook it up to a Speak-and-Spell to call the mother-ship for a pickup.
