No worries. Just wanted to make sure there wasn't some new technique I was missing. I have used a similar technique to the one Peter described. Thanks for posting the summary though!

Benny, Byron -
Apologies guys. I wasn't being reticent or unwilling to share - just been away from my desk on a 'more than full time project' - so my email backed up.

The only reason I didn't share initially to the list was that I thought it wouldn't be anything new to most members. I can see that Peter has summarised the solution - but if you'd like a copy of the project file, just drop me a direct email.

Best,


Mike

Sorry my mail was bounced several times ...

Its very simple: animate the arrow head and auto-orient it 
along the motion path. Then create a solid and apply the
write on effect to it, link the arrow position to brush position
property via expression.

It's sooo simple,
Thanks again
