The Kal-ee Calculator from Mintpass just might be the calculator I am looking for. In class, I always preferred to use my cell phone than buy a calculator, but even I wouldn't be able to resist the Kal-ee Calculator.
This concept calculator is pretty amazing. It has a transparent keypad, which means that you aren't limited to just standard numbers and symbols like on traditional calculators. The Kal-ee also comes with various calculating options, ranging from calculating your taxes to your calories. Even a man as cheap as I am couldn't resist the Kal-ee Calculator's charms.
