SpiraPaint! is a free tool to create surprising spiral shapes in diverse colours and tones. SpiraPaint! creates these designs from mathematical formula. This way it gets great results in the least time.
To create these shapes you have to select a background colour, pencil colour and the number of rotations. A good technique is to superimpose one design over another. SpiraPaint! is a program without many features. The interface is minimal and not very intuitive. However, it is worth downloading to spend a short while creating the shapes. And it`s completely free.
