These things are still in use, but tend to be used in smaller theatres where they allow a single light to project several different colours. In this era of LED they are being used less and less. This video shows an existing gel roll being refitted into a scroller after it had been cleaned, and how it is loaded and then goes through its calibration and settling of the new scroll.
The scrolling gel system is also used in some discharge lights, sometimes with scrolls of HUGE sheets of gel which run in guide rails.
