“I’ve always liked tin cans,” Allen adds. “Constantin Boym made them into coffee containers for Alessi and they’ve been played out in art, but I find them to be useful and beautiful objects. The only problem is that it turns out you could probably make a new tin can with less energy than you could cleaning and grinding down the sharp edges of an old tin can — that’s the issue with reuse. I still think it’s an interesting idea, though, and I haven’t given up on it.”
