Thought this toy might be of interest - basically it's a keychain video/still camera made in China from rejected mobile phone parts, with the mobile phone firmware hacked together to make it work just as a camera. A bit flakey it seems, but the price is right - from $9 inc. shipping.

I have one in the post and will report back.
