Shake was a high-speed node-based compositing software optimized for large image resolutions without the need for specialized hardware. With a data-flow diagram paradigm, it ran on both NT and UNIX. Features included resolution independence and a host of real-time 2D animation and effects tools. Originally from Nothing Real, which was purchased by Apple in 2002 and made available for both Linux and for MacOSX after 2003. Apple discontinued Shake in mid-1999.
