OK, you are right. It’s not music related. But it will be ;) And just imagine how cool is to use something like the Microsoft Surface for making music. Of course it’s great for visual arts too. This is an interesting project. Here is a demo video after the jump.

What is Microsoft Surface?
Microsoft Surface™, the first commercially available surface computer from Microsoft Corp., turns an ordinary tabletop into a vibrant, interactive surface. The product provides effortless interaction with digital content through natural gestures, touch and physical objects. Surface is a 30-inch display in a table-like form factor that’s easy for individuals or small groups to interact with in a way that feels familiar, just like in the real world. In essence, it’s a surface that comes to life for exploring, learning, sharing, creating, buying and much more. Soon to be available in restaurants, hotels, retail establishments and public entertainment venues, this experience will transform the way people shop, dine, entertain and live.

How does Surface work?
At a high level, Surface uses cameras
to sense objects, hand gestures and touch. This user input is then
processed and the result is displayed on the surface using rear
projection.

What is surface computing?
Surface computing is a
new way of working with computers that moves beyond the traditional
mouse-and-keyboard experience. It is a natural user interface that
allows people to interact with digital content the same way they have
interacted with everyday items such as photos, paintbrushes and music
their entire life: with their hands, with gestures and by putting
real-world objects on the surface. Surface computing opens up a whole
new category of products for users to interact with.

What are the key attributes of surface computing?
Surface computing has four key attributes:
Direct
interaction. Users can actually "grab" digital information with their
hands and interact with content by touch and gesture, without the use
of a mouse or keyboard.
Multi-touch contact. Surface computing
recognizes many points of contact simultaneously, not just from one
finger, as with a typical touch screen, but up to dozens and dozens of
items at once.
Multi-user experience. The horizontal form factor
makes it easy for several people to gather around surface computers
together, providing a collaborative, face-to-face computing experience.
Object
recognition. Users can place physical objects on the surface to trigger
different types of digital responses, including the transfer of digital
content.
