"Living dots grid" Xperiment

I created this cool rig in After effects in order to incorporate it in Adobe Premiere with dozens of options to play with :
number of columns, rows, dots colors, size, spacing, random filling...
The yellow trail is automatically "searching" for another dot within a defined holdtime duration, and behaves in a really cool way sometimes, sometimes creating unexpected kind of rectangles and squares which are really graphical !

Could even live by its own forever since it is all expression based !
