Andrew, Thanks for the code however I received the following warning: NameError: name 'SinGrating2DColor' is not defined I looked through the Gratings module and sure enough 'SinGrating2DColor' is not present. I am not savvy enough to add this to the module. Do you have an updated Gratings module? Thanks, James >Hi James, >I just added code to do 2D color gratings to the CVS repository.
