The Oxgut Hose Company of Oakland, CA is running a Kickstarter to fund a production run of its doormats woven from old firehoses. They're awfully pretty, and pricey too: $175 minimum for a 2'x3' mat. As with all Kickstarters, be aware that the project may come to naught and you may never get anything for your money.
Here's Off-Beat Mama's photos show how you can build your own AT-AT out of empty diaper boxes. What a fantastically shitty idea!
I have a dozen nappies boxes sitting around, and recently decided (whether out of a fit of stay-at-home-mum induced anxiety or just total creativity) to make an AT-AT out of them. My son naturally destroyed it three days later, but once he did I was able to snap a few shots of how I set up the structure in the first place.
