This is probably the most beautiful LED ring ever. Each led on the ring can be controlled separately on its brightness and colors (RGB). It comes with pre-burned boot loader which has several built in led scripts.
It allows I2C/Serial communication from any MCU and can be serially linked to make a beautiful Art piece via I2C.
It can be programmed using standard Arduino IDE with a FTDI breakout board.

Boot loader: Optiboot diecimila
Interface: Serial/I2C/Digital pins
