[pygame] free 3D glasses in some US grocery stores

[Bill Coderre <bcbc@xxxxxxx>]

I occasionally do some 3D stuff, so I was at a local grocery today and  
was handed 10 pairs of glasses for free. Apparently SoBe beverages is  
paying at least part of the cost of the glasses.  If you go to  
thrillicious.com you can see their silly ad, played as a youtube video.

The glasses bear the "Color Code 3D" trademark and patent warnings,  
apparently to persuade you that you have to pay them to use yellow- 
blue 3D encoding. Despite this, there are more than a few free 3D  
encoding programs that do this encoding, and it's probably as simple  
as you'd expect. (Note: this is slang for "I don't actually know what  
the math is, but I think it's straightforward.")

The program I've used to make 3D images from picture pairs is called  
AnaBuilder: http://anabuilder.free.fr/welcomeEN.html

I suspect there is information somewhere in their website about yellow- 
blue 3D conversion...

Anyway, the ColorCode glasses are almost never free, so if you get a  
chance, pick some up, and add 3D to your game!
