Music to my eyes
It's the work of a Portuguese artist called Bordallo.
Now I don't about you but I can't believe nobody has thought of doing something like this before.
Which makes me wonder how long it'll be before it turns up as some kind of 'ambient idea' for noise cancelling headphones or something similar.
Keep an eye out for it at Cannes next year. I guarantee it'll turn up with a logo of some sort in the bottom right corner.
