Ptarmigan is no longer operating in Helsinki.

Ptarmigan existed as a project space in Vallila from 2009-2011 and a mobile curatorial/creative platform until 2014. We no longer exist as an organised collective, but this website will continue to serve as an archive of the activities produced as/at Ptarmigan during these years.

Processing workshop for beginners
workshop : computers : programming
10 March, 2012 00:00 - 11 March, 2012 00:00 10:00 - 19:00
part of project: Hobilabor
presented by Hobilabor

Processing ( is technically speaking a java extended class but it is well hidden and we can consider it to be nice simple open source software. Processing is one of the most popular programming environment among artists, with over 400 000 downloads since 2001. Beside openFrameworks, Cinder++, Adobe Flash and MaxMSP - Processing stands out with its simplicity and fast entry point. When one starts using Processing they are not limited to its IDE and it’s base functionality. You can easily integrate processing to other more complex code editors like eclipse and extend it with many useful libraries. Processing is good tool set for anyone interested in creative coding. Ben Fry (the Processing co founder)'s  mission statement from the Eyeo 2011 festival: “Processing seeks to ruin the careers of talented designers by tempting them away from their usual tools and into the world of programming and computation. Similarly, the project is designed to turn engineers and computer scientists to less gainfull employment as artists and designers”

This workshop aims to introduce Processing to anyone who is interested in creative coding. We are covering the very basics of the software and a few more complex subjects like form finding and multiple instances.  Since we are covering subjects quickly, it is very important to try Processing before the workshop.

NB! Bring your own computer equipped with processing and eclipse.

Workshop price: 10€ (you can pay on the spot in cash).

Programming skills are not mandatory but very helpful.


  • To introduce Processing IDE;
  • To introduce basics in software (variables, assignments, statements);
  • To introduce visual feedback;
  • To introduce objects and classes (more complex data structures);
  • To introduce output opportunities;
  • To use as much as possible hands-on training.
