This design was made just making a squiggly line to some classical symphony, (it was something in c minor) then it was taken from a sketch to isolate a square of it, then I took that and repeated it 16 times. I love that even seemingly easy exercises can turn out interesting results.

I would love to someone else do this. Go ahead and try it on your own and post it, I'd love to see what everyone else comes up with. It doesn't have to be anything in particular. Any weird abstraction will do.

It looks like some algae sitting on a pond to me
