Body Paint Festival

Hello guys, so I came across some intriguing pictures today and for the very first time I got to know that body painting is a thing.
To my surprise there is a festival for body painting.

Really! this is amazing and astonishing. Till wondering why I never heard of it. So I was hoping someone somewhere can give me an insight or details about how this came to be and where it is being practiced. Hopefully someone who has participated in the event or have withnessed it.

I do not want to rely on information from the web I want something more and I hope I can get it here.

Ooops I almost forgot here are the pictures

And the last one.....

Thanks
