My idea is to have a graphing calculator with a camera on the back of it and its able to to connect to a smartphone. The screen on the graphing calculator will display your phones apps. The camera would work with the apps as well and can send the images to your phone. The graphing calculator to use would be the TI-84 or something similar to it.
