Vuo lets media creators make interactive animations, exhibits, performances, and professional-grade media projects by connecting up simple building blocks. Media creators can use these blocks to manipulate audio input, images, layers, videos, and 2D + 3D graphics, as well as record high-quality video of the results.

Vuo's features include:

• Real-time interaction using audio input, MIDI, OSC, and Art-Net DMX integration, or Kinect and Leap Motion device input
• Sharing visuals with other Mac apps through Syphon
• High-quality video export and interactive recording
• Exporting compositions as Mac apps
• CPU and GPU performance optimizations, including automatic multi-threading, compilation to machine code, and shader-based OpenGL
• Support for new users (https://vuo.org/start), including video tutorials

Vuo has a free Community Edition. Full pricing information can be found here.
