Prime spirals using Archimedean Spiral

See this video and this article on Wikipedia. Extract from Wikipedia below.

The Archimedean spiral (also known as the arithmetic spiral) is a spiral named after the 3rd-century BC Greek mathematician Archimedes. It is the locus corresponding to the locations over time of a point moving away from a fixed point with a constant speed along a line that rotates with constant angular velocity. Equivalently, in polar coordinates (r, θ) it can be described by the equation
$r=b\cdot \theta$
with real number $b$. Changing the parameter b controls the distance between loops. From the above equation, it can thus be stated: position of particle from point of start is proportional to angle θ as time elapses. Archimedes described such a spiral in his book On Spirals. Conon of Samos was a friend of his and Pappus states that this spiral was discovered by Conon.
