I have made a little webApp that :

• Get some RSS feed, parse It (With PHP SimplePie, for caching)
• Extract Images, if found, for each item, resize it (With PhpThumb)
• Fetch real URL for each item (With PHP Curl, for example it remove feedburner proxy)
• Provide a JSON service used by jQuery Wall (With jQuery Masonry, for fluid arrangement)
• Emulate an infinite scroll for the wall, if the feed got a lot of items… (With Google Reader feed you can append to the URL “?n=100“, where “n” is the number of post you want)
• The Wall also use jQuery Mobile (Alpha release) for feed selection
• WordPress integrated JSON service for infinite scroll…

You can watch or fork the sources on Github (JS, PHP and all  included) :

If you want to take the DEMO, that here : http://www.b2bweb.fr/wall/

The two importants script files of the project are :

• https://github.com/molokoloco/FRAMEWORK/blob/master/wall/feed2json.php
• https://github.com/molokoloco/FRAMEWORK/blob/master/wall/js/jquery.wall.js
