Pablo Valbuena's work featured above is taken from the TodaysArt Festival in The Hague.
Projected onto the side of City Hall the installation was entitled ‘Augmented Space’ - in short its an amazing way to augment architecture in the field. In today's visualisation field we are used to seeing such work produced digitally using camera tracking, it is really intriguing to see it used in real space.
