There's a bit of a vinyl record revival going on right now, but for more people those old records are garage sale fodder. Here's a third option: Let Paul Cocksedge transform them into a smartphone amplifier.
Like the gramophone of old, the design takes sounds pumped out from a source (in this case an iPhone) and amplifies them for your listening pleasure.
I would stay away from impromptu "ringtone concerts" if I were you.
Cocksedge does this by heating and molding the record. He plans on doing it live in London later this month if you're in the area, and has encouraged visitors to bring their own 12-inch records to the show for their transformation. 7.00 p.m., The Roundhouse, Chalk Farm Road. Be there or be square. [Dezeen]
