#XButNotX — Design prototype for my commission of the official 10th anniversary T-shirt for https://processing.org (2011). The X was formed by placing dipoles with different charge potentials along the outline and then simulating volumetric fieldlines between those. Created with thi.ng's predecessor Toxiclibs and rendered as dichroic glass in #LuxRender.
Just got reminded of one of my very first #ProcessingOrg pieces from 2003 (11th of August, to be precise — already 20 years ago!) Initially, this was mainly for testing the alpha blending support I worked on in their software renderer, but the resulting aesthetics proved to be quite popular at the time and the piece then ended up being shown in various places/galleries and also informed some of my later work (incl. Nokia branding in 2006)...
Btw. This video is a new screen capture using Processing v4's current OpenGL renderer, with more elements and slightly different blending results, but its close enough... The original source code is here (requires only minor edits to make it run):
