For this assignment I was inspired by a rose bud blooming and I was trying to figure out how to find an abstract way to represent it. I did this by changing the colours and have a frame rate that was slow enough for the lines to look like they were emerging from each other.

I experimented with cosine and sine curves and looked at what would happen if i multiplied, subtracted, added, and divided them from each other. I ended up with the above version because i felt that it represented the idea of the flower blooming the best.
