A suggestion... I've been playing with After Effects "CC Ripple Pulse" and have been having a devil of a time trying to make things animate. When I look for video tutorials online, there's only one video... the entire thing is in German but from what I could tell if I could understand it, it's probably a great tutorial. Ripple Pulse seems like a complicated effect since many other people online can't seem to get this effect quite right either.
I'm wondering if anyone knows of a decent video tutorial somewhere online. If anyone is interested in creating one, I think it'd be a very popular tutorial. Just a thought.
