Wii Orchestra demonstration videos

When Miyamoto took the stage in a tuxedo at Nintendo's E3 keynote and began conducting an orchestra, many attendees were floored by what they saw. Whether it was something totally unexpected that managed to pleasantly surprise or something that caused the attendee to lower their head into their lap in disgust, the unveiling of Wii Orchestra was unexpected. Since its showing at E3, nothing much else has been said about it.

Well, during Leipzig the game was made available and IGN got their hands on it. In uploading two videos of the game in action, they have given us a very good feel for how speed on the player's part affects the music in the game.
