There are hundreds upon hundreds of tennis balls used every day throughout the Wimbledon Championships.
With each serve another ball is discarded into the underbelly of Wimbledon (wherever that may be...they probably just waste 'em).
These spheretastic styles encompass balls from all over the place including cricket balls, pool balls and even eyeballs.
Maybe the Wimbledon elite should check out this cluster to get some ideas of what to do with their unused balls.
Implications - My favorite ball-o-vation has to be the ballsy seating, which is a chair and table set that's been crafted entirely out of tennis balls. Users only have to worry about not bouncing away as they take a seat in this thing.
