I did find that after I posted the question, but it’s not quite what I’m looking for.

The effect I’m trying to create calls for rounded corners with some space between each “light.”

The lights change color randomly (or seemingly randomly) choosing from red, green, blue, orange, yellow.

There’s a fairly strong glow effect on each light.

The 60s computer effect is a simple grid of blue squares of different shades, with some blinking on and off.
