Experimentor Workbench now supports animations.  It’s pretty straightforward, and just like the timer you can also use the start and stop keywords (just like for a timer) to restart or stop the animation later.

animate animateMe.x from 0% to 100% in 2 seconds

You can assign an animation to a variable:

define animateX = animate animateMe.x from 0% to 100% in 2 seconds

Which is how you can easily re-start it or stop it.  There’s a new built-in sample demonstrating animations.

I hope this helps!
