I've seen one of these before
theres alot of different kinds, this one being a little bulkier. Simply put- its a tiny gramphone but the size of a large pocket watch or tea cup or saucer. It all folds up into itself, you assemble it wherever you are, wind it up, and play records!
Also this is the most steampunk thing I've seen all day, whats it doing in off topic!?
P.S. check this out!
