Bringing anatomy into urban day art, we are so impressed by these psychedelic images printed on these wallpapers. However, the coolness doesn't stop there. When a certain coloured light is shone onto this wallpaper, it brings out and defines a different element of illustration of the overlapping designs. For example, if a red light is shone, the drawings of the muscular element of the body are defined and exposed by themselves, as shown here. This can also be a fun and creative way to educate people about the human body we think.
