I wrote this script.
It records your Mouse movement and prints it on a Picture.
(This was actually a request in the IRC)

This Readme provides the basic information, needed to control the screen recording tool.
The Program will create a file named README.txt and Settings.ini.
The Settings can be found and changed in the Settings.ini
Values:
GrowthSpeed - Controls how fast circles grow.
Larger values mean circles grow faster.
Smaller values mean circles grow slower.
CheckInterval - Controls how accurate the Mouse should be recorded.
Sets the time in milliseconds between each drawing command.
Larger values mean less accurate results and less ressource usage.
Smaller values mean more accurate results and more ressource usage.
SaveInterval - Controls how often a picture is saved in Milliseconds.
I guess that one is self explinatory.
RecolorSpeed - Controls how fast it changes it's color.
Larger values mean that the color changes faster.
Smaller values mean that the color changes slower.
