This is one of the most amazing things I've seen online in a while: The Spanish band Labuat has created a Flash-based video to go along with its song "Soy tu aire" ("I'm Your Air"). As the song plays, the video streams past your screen, leaving a trail of black, splattered ink behind your mouse cursor. As you move the cursor around, the ink follows. If you click, it leaves bigger splotches. Every now and then, the trail of ink will erupt and reveal a glimpse of larger images, like a face or a butterfly or birds. It's just stunning.

The Arcade Fire had an equally cool interactive video for its song "Neon Bible" a while back. I'm not sure which is better, The Arcade Fire's or Labuat's. What do you think? What do you think the future holds for music videos, or are we already there?
