Here is another one of those abstract wallpapers. They sure are fun to create. It doesn’t really mean anything, I just made it up as I went. There were supposed to be hairs inside the flower things but after a test render they looked more like needles or cactus thorns. Unexpected and bizarre but I liked it so I left it like that. It’s not supposed to make sense anyway
The green-pink atmosphere is achieved by having LuxRender scatter colors unevenly. Green is scattered backwards, and red + blue (=pink) scattered forward. The blobs actually emit the same colored light.
Check the flower to the left. The emitting blob is hidden so most light is moving away from the camera. The light scatters and since it has to scatter backwards to reach the camera, that makes that flower’s surrounding green. If the camera was on the other side of that flower, and rotated towards it, the light would have a pink scatter since it would scatter forward (same direction as it is traveling).
You can see this on the second flower. Some light is scattering forward towards the camera and that makes the scatter pink. It also has green because some light is also scattering backwards (the light that’s moving away from the camera further into the scene).
Some space is left clear on purpose for the icons. A full resolution png is included with the .blend file.
