RoboticSolutions, the authors of CubeStormer, have uploaded a new video featuring the "LEGO PF 3D Light Show".
Built with LEGO Power Functions elements, it is a 3 axis rotation device which can produce some stunning lighting effects.
The six IR channel remote allows for independent control of each axis and the RGB set of LEDs.
When I first saw it, thought that the NXT Color Sensor might have been used to produce the light effects. However immediately after, I realized it was not the case, but some discrete electronic LEDs were used instead.
It is a construction entirely PF based, thus not having any kind of MINDSTORMS control.
