Tuna DJ Gear has gone live with their Kickstarter project to create tangible knobs for multi-touch music applications.
Their Tuna Knobs are control knobs that stick to any touchscreen and let you control DJ and music making apps like you would with dedicated music hardware
The Kickstarter project had a €12,500 funding goal, which the project reached nearly instantaneously. The Kickstarter funding project, though, runs for about a month. Tuna Knobs are available to backers, starting at €11 for one knob.
