Description: This motion features colorful straight edge shapes spread sporadically over a pink background. Subtle light and dust particles slowly move across the shapes. In the center are the words “Back to School” in a slanted text. This is a fun and colorful background that can set a playful kid friendly feeling for any setting. This is a great way to celebrate the back to school time of year! The Geometry Lesson School Motion Background is part of the Geometry Lesson Collection.
