This is pretty random, however it might have some use to someone.
Hacked this together quite a while back by modifying a webconverger iso..
The kiosk also has a little pseudo web terminal (modified old perl script), and also allows you to RDP and ssh from the kiosk..
the kiosk is pretty locked down, but was actually hoping somebody tries to hack/root the kiosk for any insecurities (you are not supposed to be able to get out of the kiosk or pseudo terminal, but perhaps the RDP or ssh functionality may have an insecurity, but I haven't found any)
This was made by doing modifications to the iso by mounting it, copying over the FS, chrooting in, and then doing the modifications that I needed to make a more functional kiosk for colocation customers. You'd of course have to be on a Debian system (webconverger is debian-based) to chroot in and make modifications, then rebuild the iso. Described here:

Anyway, the hybrid iso can be downloaded from (can be burned to CD or imaged to USB stick or HDD w/dd (or windows equiv)) from:
https://dl.dropbox.com/u/1207345/ColoKiosk-1.0-1.iso
Once imaged or burned, the kiosk just runs off the image (cannot be modified).. the browser resets itself every 10 minutes as well (cookies, history etc etc).
