LEDs Rain ?

Is the Steem Rain project open source?, If the Steem Rain project is open source and integrated into SteemPi (instead of a external website in a frame), it would probably not be to difficult to connect Steem Rain with the (SteemPi notification) leds :)
Would be very cool if Steem Rain also controls the Led lights and can make the blue, green, and purple LEDs Rain with the same patterns :)
