Came across these great looping gifs yesterday, all done by David Whyte mostly in Processing.   http://beesandbombs.tumblr.com/   All looked like fun things try in Vops/Wrangles, thought others might want to join in.   Picked this one to start with, attached is my attempt with a point wrangle ( H15 ).   http://beesandbombs.tumblr.com/post/107347223679/columns   bees_and_bombs_columns.hipnc
