I have this very mundane need: an application to fill the SD card that goes into a digital picture frame. You know, don't show photos that were on it last time, show all the photos that are new since last time, show higher-rated photos more than lower-rated ones, etc.
I was thinking about doing it with a command-line Ruby script and then I realized that this was my golden opportunity to "Write an app whose user-experience is as crazy as what they show in the movies." You know, a background that dramatically fills in as the progress bar slowly (and precisely) moves forward with sound playing "tink-tink-tink" as each file is copied.
I think I shall name the app "Enhancement Protocol"
Your suggestions for UX elements appreciated...
