Is this Google's partiality?

I was just wandering through the web when I found this website. I found it artistic, but could not understand the art as I am an Internet Marketer not an Artist. What I noticed was different for what I have experienced? This website www [dot] exactitude [dot] nl is a GPR6 website and I was amazed to see the Google Page Rank as there's nothing present on the page in text. When I saw the source code there's nothing????!!!!! Even the text only version of Google's cache didn't show any alphabet - then how come it has got a PR of 6.

Is this not PARTIALITY of Google?
