Cool Math geek Text Art: Fermat's Spiral Poster

Original image first created by Javascript, then vectorised, put the definition on it in text art, and then threw in a bunch of "special effects". The following is a definition from Wikipedia. Dont' ask me to explain, because I can't. :) Fermat's spiral (also known as a parabolic spiral) follows the equation r = \pm\theta^{1/2}\, in polar coordinates (the more general Fermat's spiral follows r 2 = a 2θ.) It is a type of Archimedean spiral. In disc phyllotaxis (sunflower, daisy), the mesh of spirals occurs in Fibonacci numbers because divergence (angle of succession in a single spiral arrangement) approaches the golden ratio. The shape of the spirals depends on the growth of the elements generated sequentially. In mature-disc phyllotaxis, when all the elements are the same size, the shape of the spirals is that of Fermat spirals—ideally. That is because Fermat's spiral traverses equal annuli in equal turns. The full model proposed by H Vogel in 1979 is r = c \sqrt{n}, \theta = n \times 137.508^\circ, where θ is the angle, r is the radius or distance from the centre, and n is the index number of the floret and c is a constant scaling factor. The angle 137.508° is the golden angle which is approximated by ratios of Fibonacci numbers.

I like the design features on the website. They enable the fitting of a good quality Print to an existing frame. This Print was of excellent quality. I would buy again. One small gripe is that the image was not centred horizontally (about 3mm out) so needed trimming. No great hardship and may have been my fault in the setting-up. Next time, I would choose to set the text below the picture to a smaller font. Overall - Thank You! Looks good in its frame - Just as expected. I had a very expensive Gallery print of this before. It got damaged - hence the replacement. It compares very well.
