Creative Applications have covered a project by lafkon which created geometric stopframe animations using granular material and a pen-plotter:
Created by Lafkon duo consisting of Benjamin Stephan and Christoph Haag, etcpp is an animation created using Processing and a Pen Plotter where animation frames are drawn into various granular matter.
The project started during a pitch for collaborative animation project and unfortunately disapproved at the very early point, which duo decided to complete regardless. It’s built upon experimental work with pen plotters, described as precise machines and not too over-engineered and easily hackable. The process began by generating different animations using Processing which were then converted to vector graphics using an autotrace batch conversion and finally hpgl coordinates. All frames are then combined into one source file with a trigger command between each frame. Whenever the trigger command happens, i.e. when the plotter pen moves into it’s zero position, it activates a hardware switch – the camera takes a photo.
Here is the animation that was produced:
