In the first locker, an infra-red sensor detected people passing by. As a presence was detected, a light message right next to the locker was trigered to catch the visitor's attention. As visitors oppened the locker, a group of cubes were blinking as if they had screens inside, and a message was written among the cubes suggesting the visitor to visit locker 212. The grass indicated towards the concept of a public space, to contrast with the privacity implied by the locker itself.

A BX-24 controled both the IR sensor and the lights. A preconfigured ligth show was programed to be displayed everytime the sensor detected a presence, and the cubes inside locker 82 had superbright LEDs inside blinking at a very short time rate to make the ilusion of blinking screens inside of the lockers.

If the user read the message go to locker 212 and decided to follow it, (s)he would go towards the end of the corridor to find a quite hidden installation inside of locker 212. Opening the locker the visitor would be received by a 3D application.

The installation in locker 212 was composed by a screen displaying a 3D cube with live input image and a joystick. Conceptually representing one of the cubes in locker 82, it contained another cube that the user could play with trough his/her movements and the camera and through a joystick composed of four switches that would rotate the cube to adjust it to the user's desired position.

Because of a Machintosh performance issue, the actual 3D cube had to be scaled down from a six-video version (one side, one video) to a single video-source 3D cube.

The technicall complexity of the installation was greater that it could apparently seem. The process is descrived below.

1. The swithches where connected to a microchip, BX-24

2. The BX-24 read the interaction from the user with the joystick and sent midi messages to a computer according to it, through a midi to usb converter

3. The computer received this midi notes into a Max/Msp/Jitter patch and rotated the cube according to the messages generated by the user

4. A firewire camera conected to the same patch was the source for the image displayed in the cube

Here is the BX-24 code that talked to the computer through midi. It is a very valuable piece of code, easy to change into any other sort of midi communication. Speciall thanks are given to Amos Bloomberg for the help in the creation of the bx-midi code.

Also here are a couple of very short videos of the installation
