Just a few short years ago, personality and PCs were like oil and water: two completely unrelated concepts that did not mix, even with our awkward attempts to integrate the two.

You may recall when a piece of tape and a Polaroid printout were all we had to show off who we were, where we'd been, and our precious moments or people. It didn't take long for software developers to recognize the power of personalization with simple tools, such as customizable screen savers and wallpapers. Suddenly we had the freedom to drape our Desktops with images of our kids, pets, hobbies, or whatever inspiration or ideology we espoused on any given day. We thought we had it good, but things were just getting started.
