There are some sites I follow via RSS daily, and there are others that I visit every few weeks or months out of neglect.
One of these sites is Colossal, a curation site of massive art installations and, in their words, "visual ingenuity". Just wanted to link to it here in case anyone gives a shit about cool artistic initiatives you won't likely find elsewhere.
Or this, which I don't even know. What.
Expect to lose an afternoon clicking and tapping.
