I worked on these shoes (I am a co-founder of the studio yesyesno / yesyesno.com) and happy to answer any questions. It was really a <i>quick</i> prototype, and we are in the process of open sourcing all the schematics and code around the project.<p>our repo (which will get cleaned up / readme shortly) is here: <a href="https://github.com/jmsaavedra/shoes" rel="nofollow">https://github.com/jmsaavedra/shoes</a>
