What are some good low-poly scene techniques? Recently I have noticed that low-poly art has really come into vogue, and I thought it would be helpful if we could collect some helpful concepts and techniques in how to replicate this style. 

How can you create pig-art styled low-poly scenes in Blender?
Well, you can:


Use Ambient Occlusion in BI
Use rougher materials
Set up the Depth of Field setting to get a tilt-shift effect
Use the ortographic camera instead of the perspective
