The clock which does not tell the time!

This huge automaton clock is the result of a collaboration by several different artists. However, it appears that they forgot to include a clock-maker and therefore the museum curator has taken the decision not to have the clock working but to activate it for 4 performances per day. While the figures are moving a recording of some music by Bach is played but it sounds as if it is just a CD rather than music made by the clock itself. What a disappointment.
