4x8 of ply painted - first coat of white
My cousin Alberto helping out w/ painting
We borrowed extension cord - Albo's neighbors are nice!
My B&D jigsaw making fun shapes - these two cuts are for the projector mount
Figuring out how to cut this shape into the ply
After I taped the layout to the board, I traced an outline for the left half. After the cut, I used the scrap as a stencil for the right cut
Sketch of the shape of the top and bottom plates, as well as holes for the plexi tubing
Realized that I could just use my projector to project my pattern onto the plywood and sketch it out w/ pencil.
Shape of main piece is cut
Hole through plexi glass.

Alberto threading a needle... at 1 in the morning
Andrew sawing.
Threading and sawing
Final pattern. Hole on the top right is where the strings fall through. Hole on the left is for the projection mounting system
More hole saw cuts!
After much construction, I balanced the thing between two tables and suspended the thread boards on the structure.
Projection mount on left is assembled. Everything precariously held up by two bowed 2x4s
Close up of the plexi tubing going through holes in wood. I gave myself room so that I could adjust the placement during the calibration
The thread is pulled down, but it isn't taught yet.
Had to remove this protective layer on the plexi. This was a pain, considering it was struck to a plate of plexi and caught on 128 strings... A borrowed leatherman FTW
After tying down the thread to make them taugh, I use a hot glue to keep the string in place, and cut the bottom off. The result was a string that went to and stopped in a plexi sheet.
This is the threading that 911 supplied for me to mount the project on. That's the depth at which the rod was screwed into the ceiling.
All calibrated and ready to be mounted...
Took three ladders, 4 guys, and maybe a little bit of cursing to get this thing up into the air.
The ceiling mounted rods, waiting for something to suspend something heavy.
Wiremap structure in place!
Here are a few angles of the project
Here's my project's placard. Cool no touch symbol, no?
Video of the project in operation. Tough to see from video, but a ball oscilating back and forth and creating a wave in a surface
Because the bottom plate is plexi, and because the string stops in the plexi, the project gives a pretty impressive experience from just below it.
Rough early sketches of the project.
