argh.. I looked everywhere and I can't find any 3d red-blue (or is it red-green) glasses.. I found some sheets of colored plastic from an ancient project of mine and I might be able to construct some, but I am not sure I have the colors right. The red plastic sheet I have filters OK (I can't see the ghost red) but the blue / green does not (I can still see both ghost images). I am not getting (much) 3D effect. Which eye should be RED and which should be BLUE? The AnaglyphRender.py was set to display not render (I had to uncomment it). It does a double render each time I clicked the adjust angle. Hmm..
