Here's what I'd like to do. Not sure if or how it can be done.

The top portion of the website is a house with scrolling clouds, but it has to be re-sizable so that the house is still in the center.

Say the swf would be 1600 wide, but someone has their screen at only 1024 or 1200 wide, so the web page would get more narrow, but I don't want the flash to just get squished, and I'd like the house to stay centered horizontally.

Any ideas where to start?
