Ubert is a new tumblog theme from fabthemes. Tumblog themes are wordpress themes with features similar to Tumblr sites. You can post different contents like, asides, link, video, audio, images, chats, quotes etc and each of these contents types are presented differently. This tumblog theme uses WordPress ‘post formats’ to manage these different content types. Ubert comes with a fresh and pleasant design and color scheme. The theme is powered with JW player, Prettyphoto etc to manage the audio and image media types respectively.
I have made screencasts showing the setup of different post types.
