Structure Systems by Heino Engel “In recent weeks we’ve been trying to really run with it, and failing a lot; we’ve been making larger structures, hollow geometric frameworks about 16” tall, and out of 12 of them 8 have broken during the making process or as they’re drying. The book has been teaching us new concepts like skew, rotate, twist, and we’re trying to apply that to our structures. The structures also reference Martin Puryear’s work – he’s made hollow structures that are rounded and look a bit like boats.”
