I can't show his smiling face, but he really enjoys being able to do a hand activity and some days can do it independently!
The strap I used to help him keep his left hand on the dowel is sold by https://eazyhold.com/

My client is using a ring stack I adapted just for him! I wedged a tube inside the container lid. Next, I attached a dowel for his left hand to grasp so that he is involved in stabilizing the materials. His left hand is spastic and typically fisted, so this is a great way to relax it while he uses his right hand to reach, grasp, position and release the ring shapes. I simply sliced up cylindrical containers or cut holes in lids to make "rings".
