I have been working with CompassCSS/SASS for over a year now. I recently had the need to create an image sprite (or one image that contains many icons) from the silk icon sets for use in a large web interface. I created a SASS mixin to make working with the files very easy. If you use CSS and especially if you are using Compass CSS, SASS, or HAML check out my mixins.
