vintage calculators with a cheat'n heart...

Looks like an unassuming ti-82, or ti-2500, but when you press those classic chunky buttons, a little silicone nubby thing underneath presses your iPhone or ipod Touch (or similar) hidden inside. The calculator display is an empty window.

iAce is a .99 cent app which is specially designed to work with the whole line of vintage calculator sheaths. It runs a powerful computer algebra system. It can do symbolic integration and symbolic manipulation of complex physics equations involving multiple variables. Utilizing server side execution, it calculates with extreme speed. Of course it also lets your friends with iAce collaborate on tests.

makes a good case too!!!

       Nice. I reckon the TI-85 was the better device.
(I've still got mine.)

       The iPhone's accelerometers could be used to simulate dodgy electronics - e.g. if you knock your 'calculator' on the desk, the display flickers.

       [hippo] that sounds like a great detail, but also a nice feature for the iPhone to subconciously send the message to be more gentle.

       Vintage calculators for a heating chart.
