Sydney's Vivid Festival (again)

This is Customs House, with a Vivid light show. Apparently you chose some music and accompanying graphic display, then as you dance or move the graphics change. But I wasn't able to get close enough to see anything except the light display, because of the crowds.
It's nice to have something getting people out and about in our coldest months, though I realise it's still warm compared with winter in Europe.
Tomorrow, I'll try to blip the Opera House or the Harbour Bridge - the lights are amazing!
