While a cloud floating overhead is traditionally heralded as a bad omen, the 2057 “Happy Clouds” released over London were simply meant to “cheer people up a bit.”

Artist Stuart Semple released these smiley-shaped, pink-tinted clouds to celebrate London industry. Comprised of helium, soap and vegetable dye, a total of 2057 clouds were launched at a rate of one every seven seconds.

Sadly, the clouds lasted only 30 minutes apiece before they disintegrated away. Then again, there are only so many smiles I can take in a day before I just need to punch somebody. [Stuart Semple via designboom]
