one of the exhibitions at the sci-fi museum was the scream booth. and yes it is exactly as it sounds you sit in a booth and at a prompt you scream and it takes your picture. one of the 4 pictures can be uploaded to flicker which is where this one came from
and outside the booth they run on a display for a short while.
by the way yes I can scream pretty good when I want to haha it was fun ... at least for me.
