NeoPixel Ring Pong
From aerodynamics on hackster.io:
The main purpose of this simple project was to create a game for the Neopixel Ring (24px in this case).
It ended up with a simple ping pong game on a ring so a RING PONG.
It is quite simple to build. You only need 2 buttons, an arduino board and the Neopixel ring.

NeoPixel Ring – 24 x 5050 RGB LED with Integrated Drivers: Round and round and round they go! 24 ultra bright smart LED NeoPixels are arranged in a circle with 2.6″ (66mm) outer diameter. The rings are ‘chainable’ – connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you’re ready to rock. (read more)
