Well, I hope they accept it. A comment on a bug seems to suggest LL isn't 
very interested in strange configurations like shutter glasses, though.

Here are my plans (should be done some time this weekend):

Preferences dialog changes to select rendering mode and adjust separation. 
Will see if there are any other useful constants to mess with.

A hotkey to switch between stereo/normal mode in Client/Rendering. I found 
that some things are a pain to do in stereo mode (building mainly), so I 
think a way to quickly switch back and forth is needed.

Perhaps tweaking colors in stereo mode. Pure red or pure cyan seems to 
create problems, this may make things like building difficult.

The updated patch will be submitted to LL

I think it's bad glasses. My cyan lens seems to filter red pretty much 
completely. But too nearby things still don't look that well. But they're 
cheap paper ones.

Digging around a bit seems to show that there are good quality plastic 
glasses that may get better results. I'll try to get some of those. Here's 
what I'm talking about:

BTW, I'd appreciate it if people who are finding places where to get the 
glasses could send me a mail saying where they got them. Since this will 
go into my viewer I'd like to put a list of places where to get them on my 
site. I'm especially interested in countries other than the US.

Hmm, actually I wonder, is there some sort of standard test for this? 
Something like the process for gamma calibration.
