As I was sitting down to plan out my abstract clock, I was craving a matcha latte so I decided to make that the main visual of my clock. I wanted to create a piece that represented time in a more abstract manner, so I decided to make parts of my matcha latte move or change in accordance to different time variables. To plan out my piece, I first sketched out my matcha latte.

As I began to code the composition, I realized that I wanted more contrast between the latte and the background. So, I added a couple of halo-like ellipses to establish a focal point around the latte.
