Art is something magical. Here is a presentation of dunes on Mars.
They was transformed in different colors, and orientated in different directions, so the dunes appear in three-dimensional 3-D shapes.
The look of an angle, seem hollow, looking from another perspective, the same dune appears to be something completely different.
These are tricks to the eye, but certainly very beautiful landscape motifs, moreover the are from Mars.
