The V Motion Project via Netorama –

This project combines the collective talents of musicians, dancers, programmers, designers and animators to create an amazing visual instrument. Creating music through motion is at the heart of this creation and uses the power of the Kinect to capture movement and translate it into music which is performed live and projected on a huge wall.

We created and designed the live visual spectacle with a music video being produced from the results. We wanted it to be clear that the technology was real and actually being played live. The interface plays a key role in illustrating the idea of the instrument and we designed it to highlight the audio being controlled by the dancer. Design elements like real time tracking and samples being drawn on as they are played all add to authenticity of the performance. The visuals are all created live and the music video is essentially a real document of the night.
