A fun combination of Blender3d for my dragon and shark ships (just a few of the 100s I have squirreled away in folders), my planet builder, my studio photos of soap swirls, a couple of NASA images from the dusty side of Orion's sword, all topped off with lens flares and LED illumination photos from Photobash.org, my go to supplier of excellent images for compositing. There might be a wee bit of eye of newt in there somewhere!
