Can you imagine a mobile-based virtual pet that could hop around without any markers or cards?  Zenitum, a South Korean company, has just created the first markerless virtual pet called iKat, using its Depth-track (D-Track) engine.

As you can see in the first video below, the iKat works very well although it is just a prototype. How does this App work? In the other video, you can see that the App scans the area and immediately creates a virtual grid in the 3D space. Then, it places the virtual pet on top of a keyboard.

For the moment, iKat does not do much but Zenitum will keep developing its D-track technology so we will see more uses of this App soon.

As soon as Windows 7 was released, Apple released three new "Get a Mac" ads that target the new Microsoft OS. Apple executive Phil Schiller claimed XP users would have an easier transition switching to a Mac than moving to Windows 7. Thus, Apple will try to take the wind out of its sales with the new « Get a Mac » ads.

Each new "Get a Mac" ad pairs the « PC and Mac duo ». The first one, called "Teeter Tottering," shows a woman who is "an XP user getting ready for the big move." Although PC character, Hodgman, says to her that she will love Windows 7, she decides also to transition to Mac. For explaining her decision, she says: "Look, I could stick with what I know, but what I know is pain and frustration."

The second one, called "PC News," shows PC character, John Hodgman, sitting behind a news desk in order to cover the Windows 7 launch. However, the field reporter interviews customers that only express how excited they are to switch to a Mac.

In the last one, called «Broken Promises", PC Guy promises several times not to have any of the problems his last operating system had. Finally, he says: "this time (with Windows 7) it’s gonna be different. Trust me. "
