This site will be experimental for the moment while I get to grips with the publication of 3D stereograms (stereographs) which can work thanks to the anaglyph method. This method uses the red/blue glasses
If you have a 3D TV that can view YouTube 3D videos then there are plenty here.
The site is helped by advertising but you can skip or cancel them as they appear.
The gallery can be viewed full screen (look for button top right)
