Prolific French composer Claude Debussy wrote "Clair De Lune" in 1890.
In the clip below, _possibly_ the pianist is Stephen Malinowski - I'm guessing that from an item in a FAQ that accompanies the clip at YouTube.
Wikipedia says, "Stephen Malinowski and Lisa Turetsky from Berkeley, California wrote a software program, entitled the Music Animation Machine that translates and shows music pieces in colored measures."
And that's what's going on in this clip. :)
Thanks to YouTuber smalin (i.e., Stephen Malinowski? Maybe. :)
