That's cool. There's no room on the trains in Australia for people to do cool stuff like that. The seats are like buses so there's a really small aisle.
I love public performance, especially when it's unexpected. I'd love to create something spontaneous on public transport - I have many ideas, but no actors.
I have seen alot more active performances though...
Where 3 or 4 guys are running up and down doing flips, it is still very impressive.
