Canadian sound production house GGRP decided to go seriously low-fi for a promotional mailing in 2010. They designed and produced a record player made of cardboard that came with a 45RPM single. When you got the package, it unfolded into a self-amplifying player – the acoustic design of the cardboard framework magnified the sounds that came through the needle. Best of all, it required absolutely no electricity – you just spun the record with a pencil. Their ingenuity won them a Gold Lion at the Cannes International Advertising Festival.
