Germany-based artist Heike Weber needs only two tools in her work: permanent markers and endless patience. The artist decorates large spaces by tracing thousands of loopy lines on the walls, floor, and sometimes even the ceiling. Some of her installations measure around 5000 ft!

Heike starts her work by drawing the pattern on a sheet of paper, and then transfers it onto the surface. By carefully adjusting the white spaces, she gives a feeling as if the room is swirling. Aren’t you getting dizzy just looking at them?
