spiral generations

Inspiration

Last year I learnt about the Lucas sequence, an integer set of numbers similar to the Fibonacci sequence that starts with 2 and 1. I was curious what other sequences would be out there, and how they would behave.

What it does

Fibonachos generates a spiral to see the relationship between numbers in a Fibonacci integer sequence, which shows its order of growth and relationships to other spirals with different seeds. Change the seed values, and then click on the nacho to generate the spiral. The most recent sequence is displayed under the canvas.

How I built it

I built Fibonachos with Javascript, HTML5, and CSS.

Challenges I ran into

The Canvas arc method (for drawing circles/semicircles) defines the circle by x-position, y-position, radius, and then starting and ending angles. The x-y position is of the center of the circle. That's tough, because for each new semicircle I had to figure out an offset in order that it would connect to the spiral. Otherwise I would end up with a donut shape.
