Jason Hackenwerth weaves elaborate and colorful alien creatures out of ordinary party balloons. They may not do well in a fight, but they'll add a festive tone to your next invasion.

Hackenwerth started working with party balloons as a street performer, and now creates these enormous sculptures, the largest of which stands at 40 feet. Each sculpture uses hundreds of balloons and takes several hours to make. As many people comment that the airy monsters resemble sea creatures, Hackenwerth frequently photographs them at the beach, although they occasionally invade the cities and forests as well.
