Perhaps my biggest design undertaking has been a work in progress for the past three years...my desktop background. The project started as just a cool name-plate design for an advertising innovation class at DU, but the image's dimensions were so similar to my two-screen laptop setup that I decided to take it a step further and make it into the background for all my devices -- personal computer, phone, tablet, work computer, etc.
In the last three years, I have constantly re-worked and altered the desktop, featuring many athletes on sports teams that I follow and my favorite musicians. As the players perform well, they are added to the desktop, and if they perform poorly, their layers are darkened just as quickly.
It has truly been a labor of creative, customized love over the last three years, and the "project" will certainly not wrap up anytime soon!
