Recent project is for Anthony Nolan campaign that encourages people to join the stem cell register so that people with blood diseases can receive blood stem cells. There is a 1:20,000 rate that you'll find your stem cell match.
I made a matching card game. Each card represent paitient and donor. They look different but you can find a match with their wearing pattern that means same DNA. One card doesn't have a match. There is a mirror card instead. You can see yourself with that card. It means "You can be a match for someone"
