Use Cases for Fixed Backgrounds in CSS

The background-attachment property has never seemed all that useful to me. I have always looked at it as some sort of old school design trick from the GeoCities days to get a repeating background to stay in place during scroll. Turns out a background with a fixed position can be much more useful than that.

Some nifty examples of the background-attachment CSS property. I really like how you can use this to achieve a fairly dramatic effect with relatively little effort.
