If you want ideas (I'm Danish too, by the way! But for the sake of the others I'll stick to English.),
what about some fractals? You could go for:
"Koch's snowflake curve" or the "Sierpinsky triangle" (many ways to generate this).
Koch's snowflae curve could be generated by first drawing a triangle.
Each side of the triangle will look like this:
Now "iterate" a number of times. On each iteration, replace any straight line segment of the shape with
The triangle will then take shape of a star, its edge becoming more complex for every iteration.
In the limit, Koch's Snowflake curve encloses a finite area but has a boundary of infinite length!
Sierpinskis triangle can be generated as follows:
Start with a straight line segment.
Each iteration consists of replacing all straight line segments by this shape:
User defined values could change those shapes. Try making them asymmetric and I bet hilarious results will emerge!
