Crystal Planet
This one was made a few months back. It was an older concept I had, really. It depicts a squadron of DEEP (Dark Energy Exhaust Propulsion) Space Pods flying towards an unknown planet. The explanation I came up with (and you don't have to share it if you don't want to) is that the planet is home to an infinite amount of crystals that that can be harnessed for both data storage and as an energy source. Made entirely in Photoshop.
