Penelope Umbrico's "Suns from the Internet" couldn't exist without unwitting collaborators. What Umbrico did here was to type the word "sun" into Flickr's search engine, download the many (thousands!) of photos of sunsets, sunrises, sunny skies, etc., crop them so just the sun is showing, print them out and make this utterly fantastic mosaic. Aside from looking great, it made me think about how important the sun is to us humans. Not just in the obvious way that we wouldn't exist without it (indeed, the existence of life and civilization on this planet can be seen as an accidental result of the birth of this particular star), but that we all have a kind of personal relationship with it. Not too many of us worship it as a god these days, but we still pay technological tribute to it as if we did.
