Always looking for a way to differentiate itself from the crowd of iPod/iPhone/mobile device accessory providers Proporta has seized on the 200th anniversary of the birth of Charles Darwin to introduce two limited-edition products: the Darwin200 Alu-Leather Edge Case for Apple iPhone, and Darwin200 Leather Memory Wallet.

The £25.95 Darwin200 Leather Memory Wallet features a Charles Darwin signature on the back, so you can wind up Creationists at the checkout.

Inside the handsome leather wallet is a lime green lining so vibrant that it could reanimate an extinct species. As well as the usual pockets for cash (does anyone have any these days?) and cards there's secure storage space for two memory and phone SIM cards.
