This interesting little wrist device called the Wristlet was invented by Petr Hampl. The band allows parents to send text messages and "alarms and graphic symbols" to their children as they would with a cell phone.
The wrist band, whose prime feature is a solar powered display, comes only in pink. As Yanko Design points out, if this devise ever hits the market successfully, a variety of colors might be advisable as pink is, for the most part, associated with females.
