I think the impact was lost for me as I am at work and have small IE windows open, taking up around a third of one of my 19" screens. So I kind of scrolled right past it without really thinking. xD Oh well. It's a well done little piece, though, regardless of the 'fright factor'.

EDIT: Also, after reading HC's post below, I had no idea there was sound. My PC at work is muted.
