The Kompis is more than just a digital compass, really. It's a GPS mapmaker that lights the way to your destination. It may not be as effective as a Garmin, but it sure is prettier.
You can tell the Kompis where you want to go by hooking it up to your computer via USB, or you can mark a place you'd like to return to by hitting its "remember" button. It'll also tell you how close or far you are from your destination by cycling through colour gradients from blue to red.
So. Functionality: somewhere between "Nuvi 880" and "trail of breadcrumbs." Form: pretty darned cool.
