Thanks to Jamie Theobald (Graduate Program in Neurobiology and
Behavior, Zoology Department, University of Washington) for
contributing Labview 6 code to control gratings made with the Vision
Egg.  He writes::

  As of yesterday, my own Labview program - written for the Innisfree
  Picasso - is completely functional with the Vision Egg.  It took
  some messing around, but I can now do experiments as well or better
  than before.

  I intend to phase out my Labview programs over time - in favor of
  Python - but in the meantime it is quickest to interface with what I
  already have.  And it's created a set of tools in Labview that
  control the Vision Egg gratings.  It can't take advantage of
  everything that the Vision Egg can do, but I don't think you can do
  that without knowing Python.  And it's not a bad start, either.  It
  does everything I've ever needed with gratings (the contrast ramps
  are really nice).  It uses go loops with daq triggering for

The Labview code is in the ''visionegg-contrib'' package at the
`Vision Egg SourceForge files page`_.  Control Grating.vi is the main
program file in that package.

To the best of my knowledge, this is the setup that he uses:

Here are some screenshots he sent from Labview running on Mac OS 9.
