I began installing the show today, getting a lot done, and getting the motor in the air and working, although not yet properly wired. In the test run it all worked very nicely, with a slow movement of the pendulum describing a perfect circle. Most satisfactory. The photo shows the Grails piece as it stood at the end of the day, almost properly lit, with the rotating pendulum circumscribing the edge of where the cairn will be. (No, that’s not photoshop, it’s really what the lighting looks like!)
I’m pretty happy with the progress so far. I’ll load more of the show in tomorrow when I have a truck.
