I love this kind of stuff. Making use of the viewer's intended point of view and perspective to create an illusion.
When viewed from the targeted point, it appears as a specific object represented in space (in the example above, a line seeming to bounce up and down). But when viewed from other angles, you see how it was actually painted to give the intended effect.
