Sounds good, looks good! Some years after the first marble answering machine there comes a nice lighten table called Reactable that uses a Tangible User Interface. The Dj/VJ is putting plastic things in the right direction to perform live with a modular synthesizer. (via mail by tom k.)

About: We created Reactable Systems with the vision to redefine the way we interact with computers. Using the knowledge we gained through the Reactable musical instrument we are developing intuitive products focused on the promotion of creativity and the mediation of culture. In order to achieve this we are applying the latest technologies in human computer interaction, music technology, graphics and computer vision.

Imagine, you are at a party and the Dj is playing your tunes, a good mix, a perfect set, music you never want to forget, no problem! You can wear that music because this machine can stitch the full Dj-set visual on a t-shirt for you. So don’t wonder if you see a busy black sewing machine next to Dj turntables in your club in near future! Sounds Butter is an interactive Design group who came up with the idea to visualize sound with a sewing machine through the height of the stitches it creates. Before you clap your hands to order your super looper sound stitchi machine you have to be patient, because at this stage it is just a prototype.

The intention for this project was to make sound visible. As there is already a variety of ways in which sounds can be seen (equalizers, sub-titles, etc.), my aim was to produce a device where that representation of sound would be a physical one. I therefore used the sewing machine as the basis for the project as I feel it is synonymous with industry, and making physical products. Due to limitations in my computer programming skills this model of a stereo/sewing machine is a prototype of how I imagined the actual product would look.
