Aerodynamically-shaped cased for GoPro by Mark Frauenfelder from on 2016-04-19 16:47 (#1B2B5) Birdie looks like a large badminton shuttlecock. It's designed to accommodate a GoPro camera. To use it, you toss it in the air and the camera shoots video on its graceful descent.https://youtu.be/ks3iGxMlk0A[via]
