It took photographer and self-proclaimed space enthusiast Jan Fröjdman three months to produce a video turning NASA anaglyph images of Mars into a simulated flight over the planet. NASA's high-resolution imagery offers depth information and comes from HiRISE, a camera on board the Mars Reconnaissance Orbiter. 

Fröjdman converted the still images into panning video clips using reference points – 33,000 of them – and color-graded the images. He describes it as an effort to visualize the planet in his own way, rather than as a strictly scientific endeavor. It's certainly a mesmerizing way to spend 4 minutes.
