Confounded Box of Whistles
(It was the architect Sir Christopher Wren who famously referred to the organ of St Paul's Cathedral as a "confounded box of whistles". Wren had already designed the case into which the organ would be built, but the organ builder, Bernard Smith, wanted to include extra pipes which wouldn't fit into Wren's design. Although not intended as a compliment, it is actually quite an accurate description of a pipe organ.
