These are both acrylic paint on canvas which are then lasered by the mighty Glowforge. The top one started out as a black 8.5 by 11 canvas and the bottom one was a 10 inch square white canvas.
My inner child has always had a deep and abiding love for spin art (I mean, throw paint at a spinning canvas? Hell yeah!) So I used an old fan and took the fan blade off, made a flat base and some attachment doodads and put it where the fan blade used to be. I glued it down to some Plywood so it wouldn’t wobble and put the whole thing in a cardboard box to catch splatters.
First I set up the white canvas and went to town like a monkey in a zoo. Fling blobs of acrylic pain until happy.
By adjusting how long you aim the spray paint at the same spot, you adjust the number of “tendrils” of paint you will get. Much easier to get concentric circles this way.
Since this one started life as a black canvas, I didn’t need a top coat. I just went back to MidJourney and made whatever this thing is:
With the visible height of the paint under the black, I wonder how this style would work if you reversed the engraving (so the edges were all exposed)!
hmmmm
