Ridiculously likeable work from Penique Productons.
This motley crew of Barcelona boys basically cart themselves around in a pick-up truck, taking over building sites with their large scale flash-mob parachutes which then inflate, suction-blanketing various interiors with a layer of super-bright colour (a bit like The Blob, actually.)
Here's what they have to say for themselves:
The projects include the creation of colored inflatable completely occupied spaces erected by others, giving them a new identity. A simplification of the space that unifies the forms and textures, creating a different atmosphere. The balloons are constructed from regular patterns and adjust to the specific characteristics of each location. It works the relationship between fullness and emptiness, creating a dialogue with the space temporarily inhabits.
Pointless you say? Nahh. These guys have pretty much proved to me that you can spend your life doing whatever the hell you want.
