Srika's non-post-processed thread got me thinking. How about a thread for the opposite: photos you've deliberately applied lots of effects and processing to in order to achieve a look.

Guidelines:
A) Has to be based on a photo (this is a photography forum after all).

B) Avoid HDR since we already have quite a few HDR-specific threads.

C) Run-of-the-mill 'chopping (adding/removing objects) doesn't count unless you think you've got pretty damn creative with it.

Some starters...
