His name is David Bernal, aka David Elsewhere.
His participation in Kollaboration, a show for the enrichment of Asian Pacific Islander American identity, created a viral sensation that was, up 'til then, virtually unheard of.
This video has probably been viewed several hundred million times, but it's been stolen and reposted so many times it's hard to get an exact figure.
Pretty sure I'm responsible for a couple million of those views though. I showed EVERYBODY when I saw this thing.
I even bought his 'Detours' dance documentary. Still have it. Still watch it.
After the widespread popularity of this video he got hired to participate in a variety of projects:
The legs underneath Gene Kelly in this Volkswagon commercial
Danced as The Mad Hatter in Tim Burton's 'Alice In Wonderland'
And this weirdass, but interesting music video for the band Kinky
