 This lab is to some extent based on Chapter 4 in the textbook, in particular sections 4.2.1 "Points and Cartesian Coordinates" and 4.2.4 "Vector Operations".
-The main focus here is to learn how we can use other coordinate systems to help us generate effects or behaviour that would be unintuitive to get with Cartesian coordinates.

 So the coordinate would be like (angle,radius,angle) = (Θ,r,α)
 X coordinate = sin(α) times cos(Θ) times r
-Y coordinate = cos(Θ) times r
+Y coordinate = cos(α) times r  // This was Cos of Θ, which was wrong :(
 Z coordinate = sin(α) sin(Θ) times r
 </code> And find some interesting way to make the spherical movement random :-)
