While setting on my butt trying to get over the worst head cold I have ever had, I have been playing around with Google Sketch up. If you have a problem with your spouse visualizing a verbal description of your imagination, I would recommend it very highly. You can produce a 3D solid model of your thoughts. When completed, you can pan, zoom and/or orbit the drawing in 3D solid and view it from any angle.
The first image is a photo of the composting area.
The second image is the conception drawing of the composting area ( after the fact).
The third image is of my gardening area included with downloaded trees to represent my orchard. I can pan, zoom and/or orbit any area of the drawing just as the composting area.
