Hi! I'm Gary Oberbrunner; I'm an experienced tech executive and software developer. I've started a couple of companies, most recently Dark Star Systems where I made BioViz Studio, and I won an Emmy for Sapphire Plug-ins. My professional CV is here or LinkedIn. I like to build things. I'm interested in visual effects, image and video processing, and GPU computing. I sometimes write about climate change, Covid-19, tech, music and physics. This is my personal blog with thoughts on various topics.
