If you had asked them, most of my high school teachers would have called me an unmotivated student or said that I lacked discipline and didn’t take learning seriously. And yet, that abandoned storage bin told another story: with the aid of my calculator, I’d crafted narratives, drawn storyboards, visualized foreign and familiar environments and coded them into existence. Texas Instruments unwittingly embedded a flexible programming environment into a ubiquitous technology accessible to (and even required of) most high school students. These devices not only fulfill their conventional role as tools for calculation but can also support more subversive uses. The TI-83 and its kindred are Trojan Horses, sneaking in subversive education under the auspices of convention.
