Wybron makes scrollers of many sizes, so it could've been them. They make large-format scrollers and such, including one for S4 Par strips, one for 8-lights, one for 9-lights, and a "large-format" scroller for other large fixtures.
Could be about any single cellcyc that could house a scroller thus become a cyc with multitides of options for color.
EEK! where I work just purchased a large amount of single cell cycs for some show, are we working on the same project?
That's a late night joke attempt. Lots of single cell cycs on the way for some unknown project but for this or any project I have ever heard of, I'm not aware of anyone ever mounting a scroller on a cyc light. The general idea of a cyc light is to do the color blending by way of the fixture and it's primary colors not some scroll of gel which would scroll not blend. Scrolling between colors is by far different than blending to them. Could work but it would be very different in a using a PAR instead of a Leko type of way.
