Digital Postcards?

I've already seen a few things in the same sort of area, cheap single-use digital cameras which can take stills or video. Will hunt out the quick-pic of one I took with my own variation, the low-rent (but handy for when you haven't anything else) mobile phone camera.

High-tech digital postcards - ones with built-in flat screens that can play a slide show of photos taken by the sender. That's the vision of Stuart Calvey, a 22-year-old industrial design student at the University of NSW ... Calvey's Snap+Send Postcard, a disposable digital camera, is so light and inexpensive it can be sent in the mail ...

The palm-sized camera-cum-postcard, housed in a cardboard shell with a two-megapixel lens, a 10-centimetre screen, digital memory and an internal battery, would cost about $25.

There would be no delete or zoom functions and it would be one-use only. "You can't get too precious about certain features," he says. However, the slide show could be watched a few hundred times and the camera could be taken to a developer to get the photos printed.
