This is a VERY early alpha-stage version of the webkit based CP I am working on. So far I have only made 2 widgets, and they are very simple. The CP is also buggy and unfinished, so try at your own risk. Extract the below archive to a ext2 formatted usb stick and boot the chumby with it pluged in. You must have already set up wi-fi in the old flash based cp (sorry, getting to that). You will be greeted with the new cp. Press the chumby logo to see your widgets, the green plus to install new ones, ans the gear to access settings (not implemented). The top button toggles cp/widget view. It is necisary to press the top button after loading a new widget from the cp to see it.
UPDATE: see post 13 for latest version
