For the show I am designing we can't afford colorzers but I want texture, so I came up with this solution. I am scribbling on the gels with colored Sharpies! I tested it out today and it works just the way I wanted!
ah, ok we used one of those (crystalized stuff inside a gobo that spun) a couple of years ago for "The Wiz" i thought it was called something more like prizmatic or something like that... I am looking on that site right now.
Ya, it looks like a colorizer is something similar, but does not necessaraly move like the one we used did (the plastic/glass inside tumbled arround a little when it spun). Thanks!
