Yargh. Leopard only :\ The screencast they made of the screencasting software looks phenomenal, I must admit. Very well thought-through, useful features.
Any testimonials to its speed?

I've been looking for something like this for quite a while. I miss having Gspot from my Windows box.

YAY! New version has Sparkle! Many thanks to the dev :)

Good idea for 90% of the app, but downloading things from their wallpaper-RSS feeds is kinda buggy & very slow (could be the hosts there, though), and eats up a ton of processing power when it changes the background. No clue why. I'd love to see a correctly-implemented similar application, but oddly enough I haven't run across any yet.

My personal favorite BG app lately has been Wallpaper Clocks. Small processing, & makes my desktop useful.
