Delay and Repeats Parameter

[kimfucious]

This is neat; thanks for sharing.

There's a couple features that I think would make this even better.

1. Have a delay paramter, so that the text starts in the initial idle alignment position, and only starts to move after the delay has been met.

2. Have a repeats parameter that allows for the setting of the number or repeats, including infinity.

It looks like this PR woud take care of the delay bit.
