Feldar is a 2-way radio from Jian Guan which uses red LED’s surrounding its case to indicate the direction of other radios. The addition of a compass and its disregard for GPS signal makes its a low cost choice for hiking, skiing and other long-ranging outdoor sports. That said, I can imagine a bunch of 10-year-olds having a crapload of fun playing in the woods with these; even Jian himself calls them Walkie-Talkies.

Its a cute concept, I wouldn’t call it practical though. A 6″ disk isn’t exactly compact.
Your rendering is out of scale too. The wood planks make it look like its 18″ in dia.
