Lego Grand Piano in action

Just finished this Lego Ideas set so thought I'd show it in action. This happens in two ways - one the app plays the music and the keys go up and down, and the second you choose the music and then tap the keys in the right rhythm so the app will play the tune. The mechanism does stick quite often though that could just be my building skills!
