This Gravity-Defying Video Of S.F. Without Hills Is Just Crazy

What would San Francisco be like without its iconic hills? Good question. Local performance artist and dancer Karen Cheng and filmmaker Ross Ching created a video that seemingly twists reality so that the sky-high S.F. streets appear flat. The result? Trippy, mind-bending shots that — while impressive — may also give you a case of vertigo (but it's worth it, we swear). If only they could make this happen for real. Take a look at the cool GIFs from the video, and get ready to see S.F. like you never have before: flat as a pancake.
