These cases are stunning; they remind me of hot-wire work in our woodwork class when I was a teenager.

Grove is the Portland company behind them and each case is made from bamboo, laser-cut and hand-finished, so no two are the same. Costing NZ$125, they ship worldwide.  The cases are made for iPhones only and you can get the old and new shape. My favourite would have to be Birdland.
