Show IH: Free (and stock!) Cinemagraphs

I've just launched www.clipstill.com which provides free cinemagraphs every month for web and marketing, as well as reasonably priced stock cinemagraphs. The library is fairly small at the moment but I'm adding to it on an almost daily basis. I'd be interested in any feedback on the site and thoughts on cinemagraphs in general. Also, looking for ideas to get more users!
