Currently, all circles will update their direction (repeatRefresh) at the same time, after the set duration. Is there any way I can get a more organic feel and have the update in direction happen at different times for each circle? In other words, the circles would start moving at the same time but would update direction at different (random?) times. I tried 'staggerTo' but couldn't manage to get it to work.    Thanks for your help once again! Caroline See the Pe
