What are these visual phenomena?

I have the perfect question for the hive mind:
Does anyone know the name for and reasoning behind the following visual phenomena:
1 The patterns you see when two fences (or any repeating "grid" of objects) pass each other (or appear to pass each other due to parallax) slightly out of phase. I was told the name for this and it bugs me that I've forgotten it.
2 The odd wobbling about you see in LED clocks when eating or (even more pronounced if you can do it) when "rolling" the letter R.
The name is what I'm most interested in RE 1, and the reasoning for 2!
