Way-Go flashlight - prototype flashlight and pico projector device

The Way-Go flashlight is a prototype device by Sriranjan Rasakatla that combines a laser pico projector, a GPS and altitude and heading reference system. Way-Go can be a simple flashlight - but the idea is that it can also show you which way to go (you have to input your destination location of course), and also display information about your local area while you walk with it. Rasakatla says this can be used for search and rescue parties, trekking and tour guides.
