Pipedream III is a high resolution embolograph (bubble raster) I created for the Ontario Science Centre, Toronto, Canada. It was installed in June, 2006. Like my earlier Pipedream pieces, Pipedream III utilizes a series of computer controlled pneumatic solenoids to inject small bubbles which slowly float up the tube, serving as pixels.
Unlike Pipedream I and II, this piece has 96 tubes of a smaller diameter. With this setup and some elaborate software, I can create relatively clear images, including faces (my own, to the left).
A few sample shots:
Ddesign, prototyping and installation process for Pipedream III:
As a proof-of-concept I built a prototype with 96 pipes, approximately 8' wide and 25' high. I then used the prototype for testing programs to rasterize images and display them as bubbles.
Some early results (the face you may not recognize is my daughter):
Some pictures from the rather laborious installation in June:
