Because I was a Kickstarter backer for Surprise Industries' Surprise House, I got a preview tour last weekend. They asked preview audiences not reveal anything about what's inside, so I'm just giving you this picture of the outside. But I will say that they did a nice job on it, it's not scary, and It opens to the public August 16 and runs weekends through September 14th; details here.
p.s. If you haven't been to Governors Island, the island alone is worth the trip. I was there in the mid 1980's when it was still an active coast guard base doing storm special FX for the Richard Pryor vehicle Critical Condition (trailer here).
