There is a simply way to got half floating window
(like in 3D movie) with SPM...just first mount in
anaglyph way, than apply "floating window" (one or
several time), than cut or the red or the cyan
border. You can also cut half (or quarter) of one.
Of course you can save as L/R, interlaced and else
Another solution to avoid window violation is the
gray blurred border (file "bordure floue-bis").
