Water Reuse Consortium is the one that launched publicly: a federally funded research initiative where one of my prototypes was selected, built, and launched as the live site. The next two are my own. Crossfade and Sieve are working products I designed and built to fix problems I kept running into, and I use both every day. Each page has a live demo you can try. The four that follow are from USC. They're concept work: self-directed projects where I set the problem, ran the research, and took each as far as a prototype could go. I've kept them because the reasoning holds up, and because they're the clearest record of how I think before a client brief narrows the question.
