«Welcome to the Silverchair Freak Show!
[…] Click and explore the attractions. When you are at a particular attraction, you can
walk around the room to the left or right by clicking on the right or left edge of the screen. […] There are plenty of things to look at in the Freak Show, so don’t be afraid to explore.
There are videos behind curtains, in jars, on the walls. . . The only way to see them all
is to visit all the attractions in the show.»
