GridFlow has those high-level calls ready to be wrapped for Ruby, but the
wrapping hasn't been done yet. GridFlow offers fast whole-array operations
similar to what is found in NArray, but they're currently still much
easier to use from PureData than from Ruby.

You can use PureData's [netsend] and [netreceive] classes to co�rdinate
multiple separate PureData processes. I've used that recently so that I
could run both audio and video at once (and reliably) on the same machine.

GridFlow currently doesn't have anything to do with OpenGL. If you handle
everything starting with some form of RGB or RGBA buffer then I can do the
rest of the integration.
