Hey Eric; It was a lot of fun to make. There is no plan for this or any of the other forced perspective experiments I've made. I have a left-over piece of melamine from my bench top renew that I use to draw these out. Once made I erase it and layout the next. This one started with the diamond shapes and attempting to show them shifting from 0 to 120 and 240 degrees. Then the thought was to connect them. The rest just grew from that. I finally had to stop before it grew too big for the bench. As it is the 3 long axis are 660mm. Here's is a picture of it agaist a white background to help you determine the open spaces.               


Some of my most creative moments have been when I've had to cover up an error in my woodworking.
