Leaving very little behind

My mom is 81. Today is her birthday. Being thousands of miles apart from each other, during the lockdown, we made a notion to FaceTime each other every day. She is 12 hours ahead, hence 8pm my night will be 8am her next morning. It has been 3 months since we started and this piece of artwork is inspired by our daily virtual gathering. It is made for her and by her.
