Also known as Spiral of Theodorus, this spiral draws a series of side by side right triangles with one leg having fixed unit size, and the other leg a series
Hyperbolic SpiralHyperbolic Spiral
Also known as reciprocal spiral, it is an inverse of Archimedean spiral. This means the radius grows in proportion to the inverse of angle. To avoid infinite radius, start with

Vogel’s Model uses Golden Angle as spacing between two dots. Vary this spacing number around the Golden Angle and see what the model looks like.
Vogel’s ModelVogel’s Model
Vogel’s model is closely related to the Fermat’s Spiral. Instead of continuously drawing the spiral curve, Vogel’s model draws dot in constant spacing. The constant space used in Vogel’s model
Fermat’s SpiralFermat’s Spiral
In a previous project, you drew Archimedean Spiral, in which radius increase linearly with the angle. In Fermat’s spiral, radius increases in proportion to the square root of the angle.
