I wasn’t raised in the era where tin cans with a string attached to them passed as an effective form of communication (G.I. Joe Walkie Talkies sonnn). However, I am aware of the iconic status of such a communication device and how it’s supposed to represent a simpler time when you didn’t mind talking through a can to a person like 10 feet away from you that you could just as easily talk to. Duncan Wilson worked with the original concept and the result was an updated, walkie-talkie version. From Design Boom:
The cup communicator is an imaginative digital reworking of the classic children’s toy of two tin cans attached with a long piece of string. The device is activated by tugging the cord and talking is started by squeezing the cup. The pair of cups work together and have the effect of a walkie-talkie. When one person talks, the other person’s cup plays their voice and vice versa. The device is designed to recall the children’s toy and its magic and playfulness.
