I was looking at photos of the Phobos monolith and I came across this 3D anaglyph of Phobos taken by the European Space Agency's Mars Express space probe. If you have a pair of red-blue 3D glasses, take a gander. It's incredible!
Mars Express HRSC (High Resolution Stereo Camera) image of Phobos taken on 9 January 2011 at a distance of 100 km with a resolution of 8.1 m/pixel. Use red-blue glasses to fully appreciate this image.
Phobos is approximately 27 × 22 × 18 km and orbits Mars at a distance of 6000 km above the planet's surface, or 9400 km from the centre of the planet.
