If you want to play around with the look and feel of your iPod but you don't have that hacker inclination, try one of the many iPod modding services, like iPod Mods. Besides doing repairs on Apple's portable music player, they also make cosmetic mods like changing the backlight coloring to blue, orange or green. I like green (and to a lesser extent orange) because it reminds me of my monochromic monitors from the 80s. Note, they are not just adding some colored film, but going into your iPod and changing LEDs to your requested color.
