About F.A.S.T

If you are inspired by spirals, this app is right for you. A spiral is a mathematical construct and there exists several types.

This app let's you play around with an Archimedean spiral and its logarithmic variation (Bernoulli's spiral). You can change size, dimensions, appearance, and much more.

For the enthusiasts there is a freak-mode in which you can be very creative by finding your favourite spiral. Enjoy!
