Reply To: Animated Clipping In SVG

Tweaked it a bit with transition-delay, which may or may not be what you are after. For me it falls into place, like it is now here and are going to leave it at that. I enjoy tinkering with this sort of thing, and will probably use something like this somewhere in the near future.
If you would want to explore animation with javascript, the greensock library recommendation by @amanda_ is probably the best choice. My advice: take it one thing at the time + enjoy every iteration ;)
