This page lists a few of my projects that are worth sharing. There's more on my GitHub profile, if you're interested.
AMEE is web service that provides calculation of greenhouse gas emissions and other sustainability metrics. My employer from 2008-2012. Favourite projects are "AMEEdiscover" and "Ask AMEE".
The Carbon Diet
A site created way back in 2007 that combines accurate and timely emissions measurement with social aspects to create a new approach to carbon footprinting. Now open source.
An SMS-based system for exchange of alternative currencies, without requiring special hardware or physical tokens of any kind. Winner of the Most Disruptive award at Hactivate 2011.
A system that combines live energy monitoring information with social networks, to give more context and drive continuous engagement with energy use. Built at Rewired State's Carbon & Energy Hackday in 2010.
A twitter bot that announces the latest atmospheric CO2 measurements, grabbed from the NOAA on a monthly basis. Serves as a handy reminder of the ticking clock.
A charity I worked with in 2007-8 that tries to make a sustainable lifestyle more desirable by creating inspirational (and aspirational) content and allowing people to share their own inspiration with others.
In the early 2000s, I wrote a popular guide to VRML97, an early 3D language for the web. The language is long dead, and the site is retired, but the tutorials are still available via the Internet Archive.
My PhD thesis was all about efficient animation of dense meshes, using simplification and displacement mapping, in the days before raw computing power made it all irrelevant.
