Not many artist working with code share their process. This is particularly unfortunate since most of the time the process plays an integral part in the project. To this day, and it's been around 11 years, the work of James Paterson aka Presstube still puzzles me, how it is derived and made. "Cyclic Vacuum Cannonis" is James' new project, in process, documented in detail as it's developing. All of us at CAN are very excited to see where it goes, not to mention a ton of useful tips are included for anyone that wondered how this (art/code) work is made.
