Compass/SaSS + AssetFingerPrint + jammit is a great way to what wealthfront is doing. Compass has helpers that use the Rails asset link helpers to link to images. There are sprite helpers available as well. AssetFingerPrint is a Rails plugin that tosses and MD5 into the asset link automatically. Jammit compresses CSS/JS files, and the fingerprint of the resulting compiled files are picked up by AssetFingerPrint. Thats how we roll at Poll Everywhere.
