Very interesting, Mat - thanks for sharing. I looked and failed to find anything 'expensive' about it and the fact that it doesn't work on Firefox at the moment would appear to be a bug.
The guy who made it has his own company - http://moebio.com/ His software is released open source - http://moebiolabs.github.io/moebio_framework/ "Moebio Framework is designed for modern browsers. Including recent > versions of Google Chrome, Mozilla Firefox and Safari." His 'personal knowledge base' uses a variety of this visualisation - http://moebio.com/research/sevensets/ along with other effects, his bookmarks are organised here - http://del.icio.us/moebio. Perhaps he is inadvertently using an older version of his own libraries which is broken on Firefox. Anyhow, I'm sure it's *theoretically* possible to use this to visualise Tiddlers.
