World’s Largest Calculator

This is a Nexus 9 tablet running the Graph 89 emulator with a TI89 ROM.

A friend recently showed me the joy of having a TI emulator on your phone, a very nice upgrade over the stock Android calculator.  The phone is one thing, the tablet is plain silly.

The scale makes it seem like a Fisher Price toy for engineers and scientists. The funny thing is that when blown up on a tablet the calculator is almost 1:1 scale with the real thing.
