There's a lot of denim that gets wasted around the world. Every day people are throwing out old pairs of jeans for various reasons, and even the big denim factories are discarding a good deal of unused fabric. Rather than letting all that good material go to waste, the people at Ikku have decided to repurpose the stuff to make awesome gadget cases.

As they detail here, they basically collect a bunch of discarded denim, weave it with organic cotton (with little to no dye used along the way, depending on the denim's existing color), and transformed into beautiful cases for MacBooks (13" and 15" respectively), iPads (excluding the Air and mini for now), and iPhone 4/4s.

Their goal is to have a 100% waste-free and future-friendly manufacturing process, and it looks like they're well on their way. Even with eco-friendliness aside, these are very durable and nice-looking cases, particularly the Burma Collection.
