This is amazing, only thing I thought about is what if it rains?! The fact you could also 'drink' the building is clever too, bringing the users closer to the whole experience and idea.
It isn't around anymore as it was a temporary building, shame, would have been cool to go and see it!
The drill that randomly drilled the wall was a clever idea as well, couldn't have been cheap though. I like the idea about how it would change viewing abilities as you could look through the holes and it would also alter acoustics in the environment.
