An animation to illustrate the workings of a four stroke internal combustion engine. Grew out of the wish to show how to implement rather complex pydriver setups in Blender.

Took some time to get the sound right, but I am happy with it as it is now, especially because I finally managed to find the correct settings to actually produce a file that will show up as HD on Vimeo with audible sound.
