As if You Needed Another Distraction ⇥ reddit.com

Reddit user “Builderboy2005”:

In development for several years, I have finally released Portal for the Ti83/84 calculator! Written using the Axe parser, you can now play through 38 different test chambers, using Portals, cubes, buttons, and other elements from the valve game.

As someone who struggled with creating a basic TI-83 interpretation of “Snakes and Ladders“, this is incredible. I don’t have a graphing calculator kicking around, but you should download it and give it a whirl. It looks very impressive.
