I have a new test version of Dark Matter running on my own blog. The new feature is an AJAX slide carousel browser for thumbnails. In the photo stream tab there are now left / right buttons. Clicking them allows browsing through the entire collection without refreshing the page.
The code is still kinda rough so I'd appreciate some people testing it. I have tested it in IE7, Firefox and Safari.
I might have overlooked things which is why I hope some people will want to play with it. Let me know if you find any quirks! I hope to release this feature soon!!
