To escape from the heat over the weekend, I went to a great exhibition at the V&A. If, like me, you like to know how stuff is made, this is the exhibition for you. It's called The Power of Making.
Everything from dry stone walls, giant apes made from coathangers, a prosthetic suit for Stephen Hawkins, and some really cool examples of 3d printers - it's all in there!
3D printers are like something from science fiction and there was a video of a Maya mesh being printed into a cool toy. But wierdly enough, the thing that I was most impressed with was the drystone wall.
