Generate CSS Sprites on the Fly with Lemonade. Lemonade is deprecated from now on.
I’m working on Compass Sprites with Chris Eppstein and Scott Davis from now on. Lemonade’s goal as a sprite generator is to be incredible easy to use, so you’ll use ist for every project—just because there’s no overhead. It needs no configuration, no Rake task, no Photoshop, just a little change in your Sass or SCSS files.
