One obstacle in the way of the vinyl LP resurgence is the lack of record players in American homes these days. Vancouver ad agency Grey Canada has a novel solution: turn the record sleeve into a record player.

So I assume the sonic fidelity won't exactly meet audiophile standards. But if you've always wanted a record player you could fit in your Trapper Keeper, here it is.
