Hello again,

writing a spiral sketcher from scratch was quite a challenge, but I did it. My first serious Java Applet!

Congratulations?

For the mathematicians in the audience:
The spiral 'angle' is the angle the tangent makes with the radius vector. This defines a logarithmic spiral.

The formula I used:
theta = log(radius) * tan(angle*PI/180);

For the programmers:
I used a JSlider to control the spiral angle. JSlider is a strange beast..
The spiral is in reality a GeneralPath consisting of 250 to 1000 lines from point to point. The spiral is painted in XORMode.
