He was working in Australia and travelled round Asia back in 2003 or so. The first shots were from then. A couple of years later, someone paid for him to go round the world shooting more footage, then earlier this year, the same people funded him getting footage of those who'd emailed him joining in his dance.
Dude started doing this a long time ago just on his own dime and set up a site for donations iirc. Became somewhat of an internet celebrity in the early-mid 2000s, but I never here much about him. he travels light and extremely cheap usually. Its awesome he s making a living off traveling now.
