A new day, a bunch of killer new deals. This week we’ve got comprehensive lessons in the Unity 3D game engine, a toolkit for running Windows on your Mac, a gorgeous soundbar with optical audio, and a lifetime of virtual private network access, all for massive discounts of between 56 and 93 percent off. Take a look:

A zombie survival game called Apocalypse Rising doesn’t sound like a story that should have a happy ending. For game developers Ethan Witt and Gus Dubetz, this doomsday is not about plagues, oceans of blood or even the walking dead.

This apocalypse pays for college.

Yesterday we reported that a number of new iPad adopters are taking to Apple’s Support Communities forum to voice their concerns about its operating temperature. Many feel the new slate gets a little too warm during prolonged use, and they’re concerned it’s a serious issue.

Thermal imaging has now confirmed that the third-generation iPad does indeed get around 10° Fahrenheit warmer than the iPad 2, but it’s really nothing to worry about.

Thanks to its front-facing camera, the iPad 2 is capable of producing a glasses-free 3D effect using head-tracking technology. Jeremie Francone and Laurence Nigay from the Laboratory of Informatics of Grenoble at the EHCI Research Group have used this technology, along with some really basic applications, to show off what the iPad 2 is capable of when it comes to 3D.

We track the head of the user with the front facing camera in order to create a glasses-free monocular display. Such spatially-aware mobile display enables to improve the possibilities of interaction. It do not use the accelerometers and relies only on the front camera.

The video below demonstrates how the concept works, and I think it’s really impressive. I can’t wait to see how developers might use head tracking to create a 3D gaming experience.
