Slit-Scan Studio lets you create bizarre, fascinatingly distorted movies using three separate techniques:

1) A simulated slit-scan photography technique (see http://www.youtube.com/watch?v=NSesvu_uqLo).

2) A method that derives a series of level-based masks from a different image or movie and uses those masks instead of a moving slit (see http://www.youtube.com/watch?v=yaJ-QuwlKGA).

3) A method that's based on the slit-scan technique used to determine who crosses a finish line first (see http://www.howtospotapsychopath.com/2012/06/26/elastic-athletes/ and http://www.youtube.com/watch?v=v8FzjfOuP6A).

In slit-scan photography (aka "strip photography" or "scanner photography"), rather than opening and closing a shutter, you drag a narrow slit across the film from one side to the other over some period of time. Stationary objects look normal, but moving objects become distorted because they are in different places as the slit passes over different parts of the film. (For more information, see http://trevoralyn.com/Slit-Scan_Movie_Maker_Samples.html)

Slit-Scan Studio lets you open a file, choose a slit width in pixels, choose a slit travel direction, and then generate an output movie. It also lets you explore mask-scanning and finish-line-scanning.
