It's a basic virtual piano. I created it's in the Scratch, but converted it into HTML using HTMLifier. I translated it from Russian to English and published it here. Controls: Mouse, D, F, G, H, J, K, L, P, Touchscreen, Mouse. Cheatcodes: WhiteBackground, Voice2569, Space7896, NormalBackground. This project has more latest version than this, but its broken. Maybe later, i fix it and publish here.
