purchased and installed My Living Desktop (then called Serene Screensaver) the first day I bought my iMac (November 2007, I believe). It is absolutely the best "Desktop" I have ever seen or used, Apple, or otherwise. In fact, when I upgraded to Snow Leopard, the first software I purchased was the upgrade to My Living Desktop. It is even better than my previous version! More scenes, more sounds and upgraded features. The folks at mylivingdesktop.com provided excellent customer service, as well (something you very often don't get with most software vendors). I would definitely recommend anyone with a Mac purchase this application! I promise, you will not be disappointed. I am certainly not. Thanks!
