This theme (recycled canvas v0.9) is an experiment. Not just in design, but in experimental methodology, sharing, and process. The license the the theme is offered under is not a creative commons, gpl, or anything that you are probably familiar with.
Essentially if you use the theme you agree to install a wordpress plugin that collects some data and sends it back to us. Mostly we’re after mousetracking data - the x,y coordinates that your visitors send their mouse tails to. This data will be completely available for anyone to see. The intent is to use this for academic research in how people share designs, use blogs, and a variety of other purposes.
The theme is obviously not for everyone, but if you like the way it looks you have the added benefit of contributing to some research here at MIT and (in the near future) getting some neat analytic data about your site.
