The diagrams look along the lines of this:
My first drawing was done in pen and ink, making a mandala of sorts. I used some blocks from the diagrams and invented some of my own.
The next experimental step was to add some color and a few more elements that deviated from a strict grid. I started by painting a grid of squares and triangles in different colors, then I drew some design lines on top. The background square were done in Turner Acryl Gouache, so they have a matte finish, but unlike regular gouache, I can paint more on top of them without rewetting and disturbing the base layer.
I used darker iridescent colors to fill in some of the design areas.
And more:The last step (and the scariest, since there is no going back once started) was to paint on fine black lines everywhere. I think it came out pretty cool looking, although it is tough to capture the colors and the pearlescence in a photo. I have no idea how to finish it. It's on 12 x 16" canvas, and the design goes all the way out to the edge, so I think I'll have to mount it onto a box frame... so I can hang it on the wall space I don't have. :-P
Let the experiments continue!
