Back in 2011, Kirstens Viewer for Second Life added an Anaglyph 3D view capability which could be seen with red/cyan 3D glasses. See this blog post.
Kirstens Viewer has now been updated by Kirstenlee Cinquetti to include recent Second Life capabilities such as the enhanced “bento” mesh avatar skeleton and still includes the 3D anaglyph view capability.
