Several images showing the environment on desert wind-blown planet and mobile mushroom-picking and processing refineries that race across the surface for the best catch. Each man-made edifice is roughly 20 stories high, so you can imagine the strength of winds needed to propel them along. Every structure is encased in metal magnetized mesh ball and levitates inside. Large sails are deployed to catch the winds.
This is a project which my friend Kenan Tuzi and I entered to CGSociety SF Environment challenge several years back and won in team category.
