Similar to the previous “lines in space” project, for this project, we were supposed to make a sculpture that utilized “planes in space.” I decided to make an “analog computer,” if you will. I created a CPU tower with two holes in it, one at the top and one at the bottom. Also on the front of the tower, there is a command prompt window asking the user to “enter input.” This is done by sliding the tabs in the tower’s top hole to one side. By doing so, a panel slides down the tower and becomes visible as a “program window” through the tower’s bottom hole. The user can then “change programs” by sliding the tab on the left side of the tower back up, locking it in place with the tab that had been slid to the side, and sliding a different tab to the side (dropping another panel).
