Easy floatable grid structures for Rails. Don't have too much data to display but still need to fill up that screen? Why don't you present your data in a grid of boxes. Provided you color them right, boxes are very easy to the eyes because the mind understands its structure. Add to that custom coloring, (e.g. each controller can have its own color) background images and clickable boxes and you have a navigation that is not only great looking, but is also very easy to use on touchpad-enabled devices such as an iPad.
