Unfortunately, mini Leica cams don't exist, but Minox has made this beautiful digital point and shoot, which is about a third the size of the retro cams it takes its inspiration from, such as the Leica M3.

And it may not have Leica specs (its only a 5.1 megapixel CMOS sensor), but it also only costs $180, so manage your expectations accordingly. [Photojojo via NotCot via FastCoDesign]
