Given that its timekeeping capability rivals actual... you know, calling
as the mobile phone's most important function in our lives, we figure it's a function worth embellishing just a bit. Why stop at analog or digital? Che-Wei Wang's "Haptic Clock" Java app features a cool looking (if not obfuscated) display of the time, but even better, it vibrates the time to you every fifteen minutes using a sequence of long and short pulses. The feature can be manually initiated by pressing the 5 key, too, so we could even see some value for vision impaired folks. Grab the app from Wang's site, but beware -- as the developer himself points out, it works a number on battery life.
