Yeah, whoa. Back in 2012, filmmakers Kevin Parry and Andrea Nesbitt made this music video for a song by Kalle Mattson and a project they dubbed Hypno SF. They took footage of Sutro Tower from every angle, Coit tower from every side, same for the TransAmerica Pyramid and that bow-and-arrow sculpture on the Embarcadero, using a technique called "hyperlapse spin." As a result we have these dizzying, merry-go-round GIFs, as well as some freaky, elastic footage of other landmarks. Feel free to stare at them for extended minutes. We are not responsible if this breaks your phone, or your brain.
