Finally, a Good Use For My Old Graphing Calculator

One of the things I hate most about going to/being in school are some of the exorbitant expenses for items I'm not getting much use out of.  A couple hundred bucks for a textbook barely used in class or a fancy graphic calculator is overkill.

I have a couple of graphic calculators I had to buy for math courses that are now relatively cheap, but then it was spending a week's pay for something I won't use outside of class....

I ended up syncing my bookmarks and found some links I had deleted some time ago.  One was to this video about Portal being installed on a graphing calculator.  You can download the game here if you want.
