DIY industrial design. What is a Chumby? It's really up to you.
The portable device is basically a processor, some memory and a screen. Users download widgets from the internet and decide on the functionality of the thing: Stock ticker, alarm clock, webcam viewer, MP3 player, photo viewer, GPS device, et cetera.
As the device was developed by hackers, hacking and modifications, inside or out, are fully encouraged. Should set you back $150 when it finally goes on sale.
