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 finished the first version of the virtual graffiti system, which is now fully published (including all code) on the instructables website.
We ran a demo at the blue hut youth club on Thursday where it was very well received!
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.
