We're very close to the final release of Lubuntu 14.04 Trusty Tahr. In the meanwhile you can test (or use daily) the new and revamped theme. The controls have been updated to match (a branch merge) the Ubuntu standard themes (as we told here) and lots of icons have been added and fixed. You can get it at our artwork page. Also updated the old theme links, if you want to get early versions.
