Formula Tower

At digital matters, Tobias Wallisser from LAVA presented his Superformula Tower concept. Inspired by this beautiful idea, I created a grasshopper definition for towers based on a simpler formula.

The floor plate shapes are based on this formula:

r(φ) = 1 - a(1 + Sin(φ b))

Inspiered by the work of Gramazio & Kohler, I plugged together a grasshopper definition, that generates a perforated brick wall from planar curves. Similiar studies in wood have been made recently at the Graduate School of Design, Harvard

Balmond's Sigma Code

The Search for the Sigma Code has a dense plot and relies on another imaginary narrator (not a monk this time, but) a boy called Enjil. If you have ever wondered why any prime number is greater than three will, when raised to the sixth power, leave a remainder of one when divided by nine, you will be at home with this book. -- Vanessa Thorpe, The Independent On Sunday - 13 September 1998

You get the sigma code of a given number n like this:
1. Calculate the sum s of all digits of n.
2. If s is smaller then 10, s is the sigma value.
3. Else set n=s and return to 1.
With this definition it is possible to calculate the sigma values of number sequences. The result of some simple sequences are beautiful patterns:

This diagrams you obtain from the Fibonacci and the Pell sequence by using (and modifing) the following script:
