Hi wes41190,
Yes I can give you a good example. If you've seen the finalist video for Jarvis Morant - My Hump, it's done there a few times. Right around the 1:50 mark, a couple times in the 2:24-2:30 mark, and a few times at 3:19-3:36. It's like having the coaster move forward and backwards at a fast pace. I'm probably not saying it right but if you take a look at the vid you'll see what I'm trying to explain.
Thanks,
CSC
