On the left you should see 2 blocks "My updates" and "iSpot images". These are produced by an experimental "json_feed" module.
The module currently supplies 2 JSON feeds, a generic site feed and an example iSpot image feed (with callback, count etc.) (a snapshot of data from the iSpot image feed - big 1.4 MB), a Javascript, and the example blocks/widgets that you see here.
I thought this would be interesting for sites like iSpot. I'm trying to keep the module generic - the idea being that one could extend it for things like iSpot images.
Currently the JSON feed format is a subset of the Twitterformat - eg. the "text" property is limited to 140 characters. This needs review.
(Inspired by the Twitter-html, and YouTube video bar widgets.)
