The Mars Trilogy mosaic - 588 images inspired by KSR's books

This new Mars Trilogy mosaic is my kaleidoscopic vision of the incredible wealth of the Kim Stanley Robinson's martian books. 588 pictures gathered here as a sort of eye mandala with the 3 colors of the terraforming stages.
This giant mosaic full of details is an ambitious new take on a first attempt last year.
The images come from various public domain sources (a lot are from NASA) and from my personal photographs, 3D models and photomanipulations. The majority of the images have been through a manipulation process to stick as much as possible to the Mars theme. For instance, I had to give a brown sky to almost all the photos that had a blue one. This whole work of gathering images and caring for all the details and tones is a huge process along the past 6 months.

Here the file is 2000 pixels large, but the original version is very very big, designed as a mural whose details would still look sharp if printed by 5m large! This mosaic is the biggest piece of my current Mars exhibition in Grenoble (see previous news) where it can be seen printed at 2,50 wide.

Made on Ubuntu with Gimp (for the photomanipulations and crops) and with AndreaMosaic (to assemble the mosaic). The 3D models that appear on some images were made on Sketchup and Blender.
