Casual Tux is all about the Linux culture.
The Linux culture is all about openess. We want to be open as well.
But we are dealing with images, so how do we do that?
All Casual Tux images are created using an SVG format. This is a vector based way of creating pictures. In short, each line is a description of going from point a to point b. This is very much like the code that creates a program.
So we are releasing our graphics as if the svg files are code, and any png or jpg files as compiled code, or binaries.
