I enjoyed making this project as I used it to try and understand how to use sin and cos for an object to rotate around another. I decided to go with an adventurous space theme with with the earth in the bottom center and the sun and moon rotating around the earth. The sun is orange and the moon grey, both resembling the hour of the day (at 6pm and 6am you will be able to see both the sun and moon). The cloud resembles the minute of the hour and changes direction every hour. The cloud is seconds. I put the Little Dipper in the background as a nice accent to the overall picture.
