Even standing up close, Beijing-artist Li Hongbo’s sculpture of Michelangelo’s David looks like it is made out of marble or porcelain, but when it is gently pulled up, the bust stretches out beyond recognition, and when released, springs back to its original shape like a Slinky toy. The raw material that Li Hongbo uses for his sculptures is paper, thousands and thousands of sheets of paper. His average classical busts require gluing more than 5,000 sheets of paper together in a honeycomb pattern, using pressure to hold the sheets together. From there, he saws, cuts and shapes the huge block of glued paper to arrive at a rough sculpted form. Li Hongbo then shaves in the finer details and uses sandpaper to smooth the surface.

If this bridge in Oberhausen, Germany, reminds you of a slinky toy, that’s exactly what inspired it. German artist Tobias Rehberger spiraled 496 coils around a rainbow colored walkway that crosses over a canal to connect two existing parks. Rehberger collaborated with structural engineers Schlaich Bergermann and Partner to realize his design. The structure consists of pre-cast concrete plates, spiral bars and railing made of steel and net cable, all attached to high-strength steel stress ribbons connected to the inclined supports on both sides of the canal. The 1,332 foot walkway has a synthetic finish that kind of bounces when you walk. It is presented in 16 different colors, matched in color on the underside of the bridge which is made out of a different material. The Slinky Bridge is luminous with color and definitely puts a spring in your walk.
