Hi,this can be done in Houdini,i read its done in C4D with Expresso,so how can be done this in Houdini?
I love how they land but keep moving a little,and all the collisions in the path,they move like crawling,not sure how this can be done with particles

Thanks!

if you make some points boing boing on a grid, ths grid of points bouncing can be easily convert to a tube of point bouncing. with that you have 2 shape with the same points. the combination of interpolations could be with sequence blend i think. tuts from pquint on vimeo can help you.
