First animation !
This is a slightly modified version of Peter Chestna Tortoise and Hare sketch.
Only added a snail to the mix… 
That’s cool!
That’s a rather “hare-rasing” animation!
It is OK but I have yet to really dig into the code to see how the animation works and how I can improve it.
I see the a fair amount of ‘flicker’ in the 3 little cubes and I am sure that they can be improved !
Looks great, JP!
