2010 Convention - Field Sequential / Butterfield Color / Indextron
Here is a .wmv file of the color wheel in Cliff Benham's CBS test bed starting up and locking, made in 2008. This clip was shot with a 24 frame per second camcorder that converts the 24 to 30 internally for playback, so no flicker or shutter bar.
