openFrameworks is an open source C++ toolkit for creative coding.
For the 2013 SXSW festival Razorfish put Drawnetic, an application they had developed for kinetic drawing initially for smartphones, and looked to feature it at an event as a kiosk. A team had created the Drawnetic app, and even updated it so that it could work with a Leap input device, but at that point it needed to still be operated with a mouse and keyboard. Our developers supported this program by modifying the application to not require having a mouse or keyboard by relying on timers, distances and gestures to help reset between users. It was also updated to have newer branding displayed that was more appropriate for the event.
