If you've got any questions, suggestions, requests or anything else regarding these scripts don't hesitate to contact me.
Change ortho[.blend]
This .blend file shows a set-up to easily animate the scale of an orthographic camera. Normally you would do this using ipo-curves, but so far a scale ipo is non-existent in blender.
Autorotate [.py]
This script with interface creates the ipo curves to rotate an object on its 3 axes. It also calculates how many frames it takes for the object to reach its starting position again. In short: it allows you to create a continuous animation of a rotating object.
FPS camera [.py]
Move your camera with the controls you normally use in a first person shooter. More information on how to use it can be found in this post.
Material to layer [.py]
Automatically sort objects by their material to different unused layers. Note: this script won't show up in the python menu and doesn't have a graphical interface. Just load the text into blender's text editor and run it once by pressing alt+p
