I'm working on a 3d image to explain how "dark energy" is created as a heavenly body moves through space. This is a modification of the classic 2d image used to explain Einstein's theory of the time space warp. The current cone shapes will be changed. They are the wrong shape to explain the place and direction  where "dark energy" is formed as a "force". 

This is the second road test of the portable Raku Kiln shown in SketchUp drawings. As you can see the design has changed. A good friend had make the comment, " wouldn't it be cool if it were motorized". Well I've had some bike parts laying around for several years, so you know how that goes. There is still quite a bit to go on this project. I thought I'd show this because I haven't put a new SketchUp design on my blog for a while. Now you know why.

This is a design for a portable ceramic kiln for reduction firings. I'm about half way through the construction of this project. It's being built for personal use as well as for my classes.

First render study in Kerkythea. Great to get everything working again.
