One of our forum members just posted an interesting hack to attach a Mac to their Prius in-dash touch screen...

So my goal was to get a mac working on my Prius's MFD display, and be able to use it's touch screen to control the front end (currently Front Row)

I don't have audio hooked up, figured the video would be the hardest part.

I'm going through a Can-View which normally is just used for display the car's CAN data http://hybridinterfaces.ca/, but has RGB+S in and outputs the MFD's touchscreen through a serial cable.
