London Sound Taxi
Great idea. Unfortunately not quite what I expected. The sounds generated don't seem to have any connection to the urban sounds that you associate with London.
I suspect the positive response from the public was more related to the speaker spectacular car rather than their understanding that the sounds from the city affected the music generated by the car.
It would have been good to see the public interacting with the car, making sounds and getting direct feedback from the sounds created.
