I was inspired to make a harmonograph simulator by reading the book “Harmonograph” by Anthony Ashton. You can play with the settings and see what different harmonies look like when visualised on a 2D plane. Click the image to have a go!
I wrote the simulator with processing, an easy to use programming front end to java. You can download the source code from the applet page.
I’ve got a demo in 2 days, so everything needs to be ready! Lou and I built the screen today, which packs up small enough for my bike.
Now I need to put the spray can electronics in a handheld box and make the system more responsive to brush distance and nozzle pressure. At the moment it feels laggy and unreliable.
The system is going to be tested at a youth club a week today! The spray can is now wireless (see pic), and the software has been upgraded to include dripping and colour choice. A new video is here.
