I've been dreaming about this for so many years. A DIY digital camera, back to the basics of lens and sensor.

They are shipping now? Has anybody purchased one?

[edit: I guess I should have googled a bit to see that this isn't the first DIY digital camera kit commercially available]

[edit: "Low battery? Just rotate the hand crank a few times and continue to shoot your photos!" - that's also pretty cool if it works, I missed that feature in the OLPC that shipped]
