Seurat, frame 4203
The Processing sketch from which the frame above was taken now has a name: Seurat. It has controls (radius and frame rate) that can be operated by the slider (linear potentiometer) and the joystick on an Arduino Esplora board. Arduino reads the sensor data and sends it to Processing over the serial (USB) port.

The next step in this project is to build a box with lots of knobs and switches to control Seurat via a standard Arduino board.
Credits: Jeremy Blum’s blog was a great help in figuring out how to make Arduino talk to Processing. Mark Frauenfelder post at boingboing.net has a useful (and fun) video on how to make a good enclosure for the electronics.
I’ve made many improvements to the Processing code for this “installation.” There are now controls that one can fiddle with to interact with the installation as it runs. Next project: build a control box with dials and switches to operate the controls. See Seurat, Square for progress on the black box.
Code at gitHub in the seurat folder.
Below are the title and abstract for my presentation at the STEAM Factory Saturday, April 27, in Columbus Ohio (400 Rich Street).
Title: Processing Art
Abstract: We present an interactive art installation and offer a description of how it is constructed. A rapidly changing sequence of images is generated by via a computer program using mathematical principles — scaling, randomness, superposition of periodic waves, dynamics on a torus. These buzzwords and principles aside, the spectator-participant can interact with the program by tuning the color scheme and changing the letters and shapes generated. (If you like an image, we can save it and email it to you.) Code at github.
