Here’s a nice and impressive way to view and share your favorite YouTube videos with your friends. YouCube is a YouTube mash up tool that lets you add up to 6 YouTube videos to create a mash up using a 3D cube(one for each face of the 3D cube).

Once you have added YouTube video URL for each face of the cube, you can save your mash up and share it with your friends. If you turn the 3D YouCube in a way that more than one face is visible, then videos on visible faces will start playing simultaneously and YouCube will automatically adjust the volume of the videos.

YouCube is just a demo but the concept is quite interesting. While using it you might find that only two videos load simultaneously, that might be due to restriction on number of simultaneous HTTP connections, but once all videos are loaded, you can start playing with the cube.

Have a look at these Mash ups that some users created, Oo De Lally,Cube After Dentist or make one of your own and share with your friends. [via]
