When we decided a few weeks ago to host a good old-fashioned pumpkin-carving contest with our friends at Snarkitecture — and to invite more than a dozen of our favorite architects and designers to compete — we figured there would be lots of intricate, hand-drawn patterns (there were, courtesy of Daniel Horowitz’s pumpkin in the form of a brain). We knew at least one group would employ meticulous typography (ditto, thanks to Benjamin Critton Art Dept.) What we didn’t guess — perhaps naively, in hindsight — was that the designers would come armed with such an array of power tools, Japanese machetes, kitchen electrics, Arduino-coded LEDs, drywall screws, and the like. As a result, what unfolded last night at Snarkitecture’s Greenpoint studios was nothing short of amazing. Here’s what went down.
