In the wake of the second major engineering failure to happen upon
Southeastern Louisiana in the last five years, Rox Steady has produced
these installation pieces of street art. Each representing the seven
deadly sins and placed in seven different neighborhoods of New
Orleans, they are representative of the things that have led up to such
engineering disasters..
Their symbolism is timely in the wake of the oil spill that BP and their
cohorts are now saying is all cleaned up. May a swarm of locusts visit
upon their homes and zombies eat their brains…
