One of my favourite comics has become a web-to-print experiment. You can now see each page of Carla Speed McNeil's wonderful far future SF story Finder as she completes them.

Currently we're close to the end of issue 38, with two pages a week promised.

There's an RSS feed here for news of when a new page is uploaded (it behaves oddly in IE and Firefox, but aggregators cope well enough) and a LJ feed at finder_pages.
