Parents of today wish things were not so complicated without the vast advancements of technology where communications are concerned. Back in their day, all they had to do was issue a stern warning about what time to expect the kids to be home, and that's that. Plans that have been set will be seen through, without anyone breaking off an appointment at their whim and fancy unless there is a real emergency such as a funeral. The Wristlet device won't bring those days back, but it will help parents keep in touch with kids who are still too young to own a cell phone. This conceptual device is worn as a bracelet, and it is able to receive messages, sound out an alarm or show off graphical symbols thanks to its solar-powered display. Hopefully designer Petr Hampl has thought of releasing this (if ever) in more than just pink color.
