Move layers position randomly at random intervals

[Kevin Dennis]

First let me say while I’m fairly experienced with After Effects I have little to no experience using expressions.

I’m trying to create an animated background of paint splatters.
I have about 15 different PNGs of “splats”.

What I would like to do is have them randomly splat on my background hold for maybe a second or so then disappear for a moment and then reappear in a new position.

I’ve tried using wiggle and I’ve been able to have the PNGs randomly moving about the screen but they moves on every frame.
I need each to hold a bit before relocating to a new random spot.
I also don’t what to see it move. It should just appear in the new location.

Ultimately each new splat would be a new color from a palette of about 6 colors.

Obviously I can do this by key-framing each layer but I thought it would be easier to use expressions.

Thanks in advance for any help!
