Hiroshi "Gitchang" Okuno

It taught me a lot about life, that it doesn't always go your way and you have to find happiness in everything you do. Stand tall, hold your hand up high and keep on fighting. I think that's what the Olympics are all about.

Michelle Kwan, reflecting on winning sliver instead of gold
Nagano, Feb. 22, 1998.

Music makes possible the delightful symbiosis between humans and music co-player robots, regardless of generation and culture. For example, they dance, hum a tune, and clap hands when listening to music. They share the brilliant time through the music.
