Art Lebedev's concepts don't always come to fruition, but they're great eye candy even if they'll never actually exist. This round-screened Navigarius GPS concept is one of their prettiest.
The Navigarius would have the round touchscreen, USB, microSD, and a cigarette lighter adapter, provided spaceships have those. I don't think I've ever seen a round screen in real life before, but it actually looks great for a GPS unit. There doesn't seem to be any immediate plan for this thing to ever go into production, but we can still gaze and hope. [Art Lebedev via Engadget]
