This is an advertisement for the Sony Bravia, which is (I believe), a high-definition television. The paint is real (and environmentally friendly). Thanks to Eirene for showing it to me indirectly.
Oh--by the way--I present this ad not because I'm interested in the product, but because it is really quite an amazing visual performance. Apparently they used something like 70,000 liters of paint to make the commercial.
