Designer at Mintpass (mintpass.com) has turned the Windows XP and Mac OS calculators into a real stuff. Same color scheme, and even has menu headers.

The designer is aware of the fact that it would be unlikely for either Apple or Microsoft to let any third party get away with making these calculators, so is leaving it up to the two computer makers to make real-life versions of their OS calculators.

More pictures after the break.
