If street artist and interventionist Filthy Luker strikes, it could make your skin crawl. From what I can gather, "octo-pied" buildings bulging with massive tentacles seems to be a favorite theme. The above installation was done in collaboration with Pedro Estrellas, and Filthy Luker refers to it has having "tentacular cancer."
Filthy Luker has a solo show in Southampton on August 17-29 called "Domestic Fouls" at the Bargate Monument gallery. He and Estrellas also have "stuff" going up on Old Street in London at that time.
Filthy Luker has a Facebook page and a website, http://filthyluker.org/, if you'd like more information.
