AE Experiments : 8 Gridded Patterns

More experiments in random pattern making within After Effects - but this time I wanted to see if I could make the generation of shapes follow a grid layout.

Shapes would generate on pixels rounded to the 100, and resize in multiples of 100, making sure that everything would line up nicely.
The dot pattern used Repeaters with random values generated on the Copies field, to make sure the dotted area was flexible without scaling the circles.
