Imagine that you’re swimming some laps in an indoor pool, simply minding your own business, when you look up to see a pair of massive, inflatable clouds looming overhead. Or maybe you’re walking down a city sidewalk, only to have enormous clown spring out at you from in between buildings. With subjects ranging from the aforementioned gigantic clouds and clowns to equally super-sized horses and dung beetles, Canadian sculptor and installation artist Max Streicher creates attention-grabbing, inflatable pieces that he animates using industrial fans and simple valve mechanisms. While his dramatic, kinetic works must be incredible (and/or horrifying!) to encounter in person, lucky for us, they also translate into some visually entertaining photos.
