Lost favorite screensaver in upgrade to Mavericks

I recently upgraded from OSX 10.5 to Mavericks, but I lost a neat screensaver that used to toss "snapshots" onto the screen. These snapshots would eventually build up beautifully on the screen. The "Snapshot" screensaver in Mavericks is not as satisfactory. First, the snapshots are too tightly cropped. Second, they don't really build up the way I like. Third, the older snapshots fade to gray. Any way to resurrect my old "snapshot" screensaver?
