# Week 3: Oscillations & Rotation

This week I experimented with making spirals, manipulating them with concepts from Fourier transforms, and using oscillations. I began with a simple sketch where I used polar coordinates to build a spiral (*Figure 1*).

I then manipulated the radius of the spiral using concepts from this **3blue1brown** video. *Figures 2&3 *show patterns that I developed using these concepts. You can view these examples **here** and find the code **here**.

At this point I changed gears and began to focus on oscillations. I saw **this** post on the creative coding subReddit and was inspired to combine this idea with **oscillating symbol** that appears on the apple watch when you use the breathe application. I began by creating a simple oscillating circle that grows and shrinks (*Figure 4*).

I then added an angular acceleration to this object (Figure 5).

From here I created a class for each square and added many squares to the canvas. Each square had a unique acceleration and amplitude (*Figure 6*).
