This project is the result of a set of collaborations between a photographer and an engineer, in the interactive laboratory of art, science & technology called Plataforma (Bogota, Colombia).
The concept of Resbala was to make a physical picture interactive. A schema is given in resbala.pdf but a few explanations are available.
We have twice the same picture, one is cut in bands vertically, the other horizontally.
The bands are weaved as in a banana leaf roof, the vertical bands are fixed and the others bands are attached to tubes to be able to slide horizontally.
The left tube rotates due to the motor below is, the right tube rotate due to a belt connected to the motor.
The motor is controlled by an arduino which receives its data from an ultrasonic sensor to detect the position of a visitor.
If a visitor is on the left side of the piece of art, the horizontal bands will slide to the left, and vice versa.
