The Grain Theme for Wordpress 0.3 "r2" bugfix release including translation fixes and Mosaic MediaRSS support is now available for download.
As per revision 207, Grain's MediaRSS feed supports the on-demand loading feature. It is now possible to set a relatively small amount of feed entries (e.g. 25) and still have all pictures displayed within Cooliris.
This is currently SVN only, but I'll upload a new release in a while.
Sorry it took me so long.
You can get your copy in the Download section. We'll resresh the Wiki pages ASAP.
The development version of Grain 0.3 is now tagged as beta 2. In addition to the features from the beta 1, this version now sports MediaRSS support as well as different post types: You'll now be able to decide if a post is a "classic" photoblog post, showing the uploaded photo, or a custom post showing content you specify, i.e. flash video, etc.
... yep, this is still alive. It's actually quite hot.
