ctrl-p exhibition, on now in Sydney and through December too. Go down there and check out some printers and tech! http://www.object.com.au/exhibitions-events/on-now/
I love the ctrl p sign, I wonder if the stl for it are about?
They said they are uploading their prints to their site for people to download and print at home (mainly kids at schools in NSW as most schools have a 3d printer). At least the scans of people, if you ask them about the sign they may share with you.
The figure head prints were taken from scans of people of the opening night, FYI
