John has a preview of what’s going on tonight, he writes –

It’s time again for all New York City-area makers, builders, hackers and crafters to gather at the MAKE/Etsy headquarters in Brooklyn for another DIY show-and-tell night. Last month’s music-themed show-and-tell was fantastic (check out some video and photos from last month here), and tonight’s subject–all things paper–is bound to be equally DIY-tastic. Paper wallets (check out what I’m carrying now above), paper airplane folding contests, portraits done via robot, and much more awaits tonight…
