Some of the best internet videos come from creative minds with free time on their hands. Jeff Heimbuch is one of those minds, and he has come up with what is and will probably always be the best take on Apple’s iPhone 4S Siri function. That’s because Heimbuch is a fan of Portal 2, and saw how Siri could be improved by adding in a little GLaDOS.

The result is a slight alteration of the Apple Siri commercial. It’s mostly the same video you all remember from Apple’s big meeting this week, but only mostly. A very important detail has been changed, turning a simple virtual assistant into the best virtual assistant ever…

TeeFury’s latest t-shirt may just be its best. At least, gamers may deem it the best. The limited edition t-shirt for October 22, 2010 is called “True Love Never Lies” and features an original Portal-inspired design by jimiyo.

The shirt has an intricate emblem featuring all of Portal‘s most important items…

Now that everybody’s going back to school, you’re probably going to have to endure boring courses and lectures about things you will never actually use in real life. But at Wabash College in Indiana (US), freshmen get to play Portal as a class assignment.

Portal 2 is shipping with a robust cooperative multiplayer mode. This mode isn’t just two players trying to see who can complete the testing chambers the quickest. Portal 2′s co-op mode is a totally different campaign than the single-player mode, and lasts just as long.

Portal turned out to be one of the best puzzle games out there. The portal gun is an excellent idea as a game mechanic and the inclusion of the hilarious A.I., GLaDOS, as both game tutorial and storyline resulted in tons of loyal fans. Recently Valve re-released Portal for free for a brief time and changed the ending to give some hints about the upcoming Portal 2. Recently at the E3 more details about the game and a trailer were released.

Valve is so proud of its work on Portal 2 it has hailed it as some of its best work.Valve’s co-founder Gabe Newell gave a short interview with 1UP in which he stated Valve internally feels that Portal 2 is,”the best game we’ve ever done.”

Portal fans may remember that GLaDOS dictated directions to the player at all times. GLaDOS was, of course, evil and misleading, but the haunting voice was somewhat mesmerizing. You can now have GLaDOS order you around in your daily life as well, thanks to the GLaGPS created by Ryan VanMiddlesworth. Where GLaDOS stands for Genetic Lifeform and Disk Operating System, GLaGPS stands for Genetic Lifeform and Global Positioning System.

GLaGPS is a fan project, and not endorsed by Valve, the makers of Portal, but I’m sure they’d find it pretty darn cool. The voice pack only works with the Garmin Nuvi GPS so far, though VanMiddlesworth is also working on a TomTom version.
