for the moped trip I strapped a 5mp camera I have to my chest and just kind of hit the shutter once in a whole, but at one point I accidentally switched it to video mode, and took some QVGA quality videos. crunchy
The camera is a humble Olympus Camedia C-5050. It has a very decent lens on it and it runs on 4 AA batteries, which it uses in about 3 hours of continuous use.
it was a great weekend despite my bike running like garbage
