Gary Coker thinks this is interesting:

Ethan Marcotte, author of Responsive Web Design, provides an excellent walk-through of responsive design techniques, utilizing

• Flexible grids that expand or contract content based on screen resolution

• Flexible images that decrease in size on smaller screens or increase to a set maximum size on larger screens

• Media queries, which are elements of code that can be placed in a site’s HTML and stylesheet. These queries gather information about a device’s display capabilities and use them to serve up different styles accordingly.
