No Feklee, for the line animation I wanted to smooth out Acorns example (no criticism, I just thought the example "jaggy" and wanted to see if it could be smoothed).

I created a very short line (rounded ends and fairly large line width). Cloned, moved and applied a blend. Next created another curvy line. Selected both & fitted blend to curve.

Arrange/Convert to editable shapes/Ungroup. Deleted the blend curve. With all still selected, as per Acorns instructions, named them all htmlclass=animate.

This gave a very smooth animation. The donkey one was done in exactly the same manner but it just auto animated unlike Acorns version that required a button press.

Perhaps Acorn could expand on this?

I must admit it's fun to play around with but unfortunately my brain won't remember how I did it myself tomorrow!
