How does Eclipse compare to Jack?

The Jack stack is awesome. However, its very different from Eclipse. Eclipse is meant to provide your webpages with backgrounds behind your entire content. Jack sits on top of the webpage background and lives among the site content. Jack can provide backgrounds (among many other things) to your content but not really the entire webpage.

Another glaring difference is that Eclipse can do background slideshows and video. This is not something the Jack currently does.

Now go forth and make your websites great!
