Some months ago I listened to an episode whose guest was deeply involved with ZigBee wireless. One of the projects of the guest was using the ZigBee in a highly synchronized manner for choreographing the illumination of performers costumes.
I have been googling and going through podcast synopsis and still can not find the episode (so much for deleting after listening :S). I am pretty sure this was on an amp hour podcast but I could be wrong. My pool of podcasts is pretty small so at least I hope I am close (Embedded FM, Spark Gap, TEC).
A link to the episode or the guests blog/publication of the project would be immensely helpful.
