That's really really cool! Have you tried using Tony's empegface program? I think that'd be sweet. And it'd give you more control over the empeg than emplode by using just the touchpad. Even Mark's html interface would work using Hijack.

Is there any way to take the touch pad and mount it on the wall? Or get a usb type touch pad? I just imagine it being hard to type vertical like that, so having another input device would be cool.

Either way, that's a really nice project! It'd even be a cool night light too!
