[photo-3d] practical retinal rivalry

["Robert J. Vaughan" <k0mz@xxxxxxxx>]

George,
Many times I use freeviewing of documents and spreadsheet columns to
quickly find differences or errors between two similar documents.  For
example, hard to find small print legal changes in almost identical
credit card policy updates can be quickly spotted with retinal rivalry. 
Bundled legal notices in the newspaper are more interesting when viewed
this way.  Sorry that this response is so late as it needed editing.
