Anyone know..........?

There's a series of videos a friend showed me the other day when we were hanging out, and i kinda forget the name of them. theyre like musical compositions but the videos show the music interacting with a bunch of different environments. like one video shows cups flying out of one cup and into another at increasing rates to portray drums, and another is liek an electrical tower with varying lights on the tower for different guitar tones, moving with the tone. they're really cool and have what i believe is a one word name thats more or less a combination of 2 words (could be wrong),. id ask my friend but her birthdays coming soon and i want to surprise her with the 2nd dvd in their collection that she's been dying to get. any help would be greatly appreciated
