Thumblr is a browser-based Tumblr slideshow app I built to experiment with both the Tumblr API and CSS3 animations. To see your own Tumblr account, use the “Change Account” button in the upper right corner.
Try it here: thumblr.j38.net
You can also append an account to the URL: thumblr.j38.net/#coryschmitz
