lolol
im glad you ask
the number is 360 in binary code and the website is a *fake* viral marketing site for the 360
the sig should link to a game where people all over the world could move these squares in real time. It took quite a while to build as everyone ketp messing it up... idk who made the lol though 0_o
anyways that game has been taken down now... there was a login for that site somewhere but i forget.
try
http://www.101100100.com/movewords/ for an idea of the square game but with words
hope this helps in some way
