Mixamo.com has a good free Gangnam mo-cap you can apply to any uploaded model. It's actually a pretty interesting service, you can just upload a 3D model and their software will auto-rig it for you, and you can pick any animation to apply to the rig (This dance is one of them). Seems it'd be a great service for indie game devs -- not one myself, but looks fascinating.
Ah, I came to make a comment about needing 'in WebGL' adding to the title, and I see it is already there!
Little comment: If like me you try to click on anything in chrome, you will get a message about the page wanting to disable your mouse cursor. I thought that sounded dodgy, but agree. It just means let the app take control of the cursor, so you can use it for changing viewpoint.
This demo tries to capture your mouse cursor, so that you can use the mouse to look around the world. But it's malfunctioning (on Chrome, Win 7 x64).
Synopsis: the first time it loaded, I clicked on the canvas. That popped up a banner at the top of my browser window which said something like "so-and-so website would like to take over your mouse cursor. Allow or deny?" So I tried to click on the allow button, but wound up accidentally clicking a bookmark, which of course navigated me away. So I hit the back button, which reloaded the demo. But now it's not trying to capture my mouse anymore, regardless of what I do.
Just writing that up on the off-chance it's helpful to the author. The itself bug doesn't matter much, though.
You may be on to something. In the future more artists may choose to make music videos like this or Ro.Me if it's cost-effective enough. Artists have always embedded CGI stuff into their music videos, anyway.
Very nice! (Is there a way to rotate rather than just strafe-move?)
Now if there were a game that reproduced the scenes and people (including Psy) in the actual video -- and let you blow them all to pieces, stopping the music each time a scene is cleared -- that might get another billion plays!
Very creative and entertaining. I can't stop watching the middle monster.
Something I didn't realize at first was the ability to use the movement keys - seeing different angles is pretty cool. As another comment mentioned, the sync could definitely be tighter, but otherwise well done.
