German artist Heike Weber uses dozens of permanent markers to completely transform a dull space into a mesmerizing three-dimensional environment.

The artist starts out by drawing her loopy shapes on sheets of paper, then proceeds to making them permanent by repeating the process on a room’s floor, ceiling and walls, with markers. I can’t imagine how much patience you need to do all the drawing by hand, considering you’re pretty much tracing the same lines over and over again, but I guess that’s just one of the qualities that make Heike Weber a great artist. What’s even more impressive is some her installations are larger than 5,000 square feet.

Apart from using the marker’s colors, Weber’s technique allows her to control the white space between the lines, creating a three-dimensional world that somehow feels alive. I can’t imagine anyone being able to live in a space that seems to be constantly flowing around them, but if you can’t make up your mind about how to decorate your home, maybe you should try a permanent marker and unleash your artistic talent. This guy did it, and it turned out pretty darn amazing.
