This Basketball Has a Brain
It's pretty funny to think about a basketball having more computing power than any computer from the 1980s, but that point is proven exceedingly well with the Wilson Smart Basketball. This app-enabled ball tracks your speed, shooting accuracy, shot distance, and shot recognition, and allows you to review your skills in real time on your phone.
It's like the perks of having a Terminator-esque gym coach on your ass, without all of the talk of apocalypse and murder. Download the app and start playing.
