I designed the 4 panels' foundation images, and they are currently being printed out on a large format printer - 44 inches x 7 feet! As soon as these are back, they can be mounted to the panels, and then the fun begins.
The base is 90% complete. These pics show the framing of the tower finished - all that's left are some more L-brackets to secure it even more against the winds on the playa.
These pics show how the sidewalls will lay against the tower frame. Two are shown; once all four are on, you won't even see the frame!
