VFX Designer for "Moon" (2009) G. Rothery Explains the Effects

The blog has quite a few photographs and a lot of discussion on how they merged actual models and CGI for "Moon" ( http://www.imdb.com/title/tt1182345/ ).

Additionally, there are quite a few questions and answers in this Reddit thread, as well as multiple spoilers: http://www.reddit.com/r/reddit.com/comments/f50mf/sci_fi_if_...

I find it amazing how much detail and care the designers put into the set, given how low-budget the film was. This is definitely an example of how ingenuity and conscientious problem-solving can make up for a lack of funds.
