About The Dev

Hi, I'm Anthony, the psycho behind CagsCalcLabs, your source for things that should probably never be put on a TI-84+ CE. No, seriously — I have no idea how my calculator hasn't exploded by now.

It all started one day back in high school when one of my friends showed me a program on his calculator that made it draw a line across the screen. My neanderthal high school brain thought that was the coolest thing to ever exist on a graphing calculator and took to replicating it. And so began my descent into making my calculator forever teeter on the edge between perfect stability and nuclear meltdown.

In the years since then I've graduated to math helpers, science tools, games, security utilities and more. Now CagsCalcLabs is where those experiments grow up into real projects and older projects get some visibility (see the fancy cards above). This is less a business plan and more an ongoing prank on the TI-84+ CE and I fully intend to keep making the TI-84+ CE regret its existence.
