A syphon implementation for pure data, both server and client. Syphon is an open source Mac OS X technology that allows applications to share frames.  Syphon provides an ecosystem for sharing imagery between applications and new media development environments. Syphon gives you flexibility to break out of single-app solutions and mix creative applications to suit your needs. If there were only one kind of rotating cylinder and only one set of operating conditions, choosing the right syphon system would be a simple matter. Syphon  is an easy way to move liquid from place to place without using a pump.
