Zentangle
I was testing out some of the line drawing capabilities of the smaller 35W tubes, in theory because they have less power it should be a lot easier to make these marks without cutting all the way through the material. Zentangles are simple doodles using structured patterns, some people use them for meditative practice. It turns out that drawing them on a computer is equally soothing, this sampler came out really well from a bunch of simple patterns.
