Hi, newbie here all excited with my 770 on back-order...

Something has occurred to me that I don't think anyone has yet written/ported. If you could mirror the 770's display, then you could use it as the image source for a heads-up display (HUD). This has all sorts of interesting applications - especially when connected to a GPS.

How hard would it be to write a display-flipper which toggled the display around in various ways (left-right mirror, top-bottom mirror)?
