Damn, I didn’t know what does the word ‘aperture’ mean until now.
I ran into an article on Wikipedia about software called Apple Aperture, and then I was all “OMG APARTURE IZ A WORD NO WAI”, so I entered “Aperture”, and saw this image
and then I was all “OMG TAHT WAS TOTTULY IN DAT WUIRD VIDEO WEN TEH KLOCK MORFED!!11!!!1one”
And I was so excited that I accidentally pressed the hotkey for posting before I finished writing this post.
Anyway, the conclusion of this elongated and over-informative post is that the ARG creator was referring to Aperture Science in that video (no shit). :hmph:
EDIT: I already stated that it resembles a “camera objective”, but it had no meaning until now.
