The only bad thing about Portal is that you can't play it everywhere. You can't play it while camping, you can't play it in the car, and you can't play it in the waiting room at the dentists office (unless you lug around your laptop to all of these places. Weirdo).
You definitely can't play Portal in the classroom. It'll be way too obvious. Unless you're in college where the lecture halls are huge and no one pays attention anyway.
So what about the rest of us who want to enjoy all the goodness that is Portal (and Portal 2) during small, boring classroom lectures?

The game, which is only compatible with Texas Instruments TI-83 and TI-84, features 38 evasive chambers using Portals, plasma balls and electric fields.
