The Spiral or "Wave" Painting.

The mica flakes in water flow down a slight hill around an arc into a hole on the canvas which is stretched over a jig I built on a table, kind of like a ramp in a parking garage.

88 bottles are used as weights, attached to the back of the canvas with strings through the table, they act as weights to pull the painting surface down onto the jig, deforming it to the downhill shape. 60 fins form the supporting ribs. Over four curving feet, they decend a total of one inch in elevation. Each fin is about one third of a millimeter lower than the previous --shimmed with pennies, scraps of wood and clippings of plastic from yogurt containers.

This took me three years to build. As you can imagine, I am so glad it works. It takes about two weeks to prepair for each painting. Out of three pours, I have two successful paintings and one I junked.
The whole thing amazes me (:

Here are some pictures and our first video of the spiral painting in action.
