atom spiral

spiral

The atom-spiral can be used to design an e with an appealing curl like in the @ symbol.
The name has been given by the Belgian Annie van Maldeghem, named after a symposium called Matomium, held in 2002 in Brussels.


The spiral has two asymptotes, the unity circle and a line (φ = a).
The smaller a, the faster the curve approximates the circle.
