Random Grade School Art

I remember doing a project like this in fifth or sixth grade. Space time, to me, is represented in a  rather '80s contemporary way in these images. As if staring into black, or worm, holes. Some meetings recently have had me doodling along this theme. I tried to do a slightly more complicated version. The result was a merging of same radius centers forming what look like saddle points as the texture defines the centers.

Whatever it is/was, it was a good time to be present and focused on just the drawing for a couple of hours.
