Software guy for Coda Octopus, in Edinburgh. Before that, 3 years on the Discrete Element Method, for engineers (Particle Analytics). Before that, for 20+ years, I was a global illumination rendering guy (first at University of Manchester, then briefly for Fraunhofer IGD, then at Lightwork Design). Married with 2 not-so-wee bairns.
