The Gearhead column has been keeping tabs on the best Android apps for IT workers. Here's the cream of the crop
I also like the free Color Flashlight which can control the camera flash (if your phone has one) and or the screen. Even so; I'm not sure how and when I'd need to have the screen display a word such as "HELP", act as a strobe, or flash police colors. On the other hand, the animated spiral might be useful for hypnotizing users into believing that everything is working fine and that they should move along as this isn't the droid they're looking for. Rating 4 out of 5 (I also get 5 out of 5 for my "Star Wars" reference).
