This is such an awesome example of art that totally dominates a space--in a good way. This monstrously massive mural can be found at the Idea Generation Gallery on Chance Street in London, where it formed part of their Monsters Inked exhibition.

Artist Pete Fowler is behind this 'Monsterism Island' mural, which stretches from floor to ceiling. You can get an idea of the sheer size from the installation images in the gallery above. It was installed using a new material called Wallapeel.
