Hi, Thanks to François for posting the default gradients file on the list. I actually forgot to add them to the archive. When Chaoscope can't find the default gradients, it will initialize Light and Plasma modes with built-in default gradients, which are same as those found in the speed.map and angle.map files. You can modify these files if you wish. There are a few map file editors available on the web if you don't want to use a text editor to define the red/green/blue values.
