Handprint Project Leo

From the Makey Makey website: 

This amazing project was designed and implemented at the Friends School in Philadelphia, PA. The students were given a "Project LEO" challenge (LEO = Love Each Other) with the goal being to enhance community and connection among students at the school. The central staircase was turned into an interactive experience using Makey Makey. The first handprint at the bottom of the staircase was designated as "earth" (ground) and then each successive handprint going up the staircase was assigned to a different input on the Makey Makey which correlated to a pop music song with a theme of love and connection (This project was coded in Scratch.)
