Today’s invention is a massive musical instrument, based on a construction crane.
This would have several cables suspended from trolleys on the main boom.
The cables would have different weights attached, each of which would also incorporate a loudspeaker chamber (red, yellow and blue).
Using a computer to control trolley movements, these could be made to bump into each other, creating some loud chords across the building site.
It would be a challenge to write some popular music for such an instrument.
Failing which, this might be used, when not actually building, as a modern equivalent of a clock tower’s bells, striking the hour.
