This is a simple image I made when I was really bored.
I used Blender 2.64 and rendered in Cycles at 200 passes so that there is still some noise in the image (also so it didn’t take long to render). I also did a whole lot of color correcting in Photoshop CS6 and added lens flare and dust to make the image more interesting.
The technique I used to make this image was practically the same as the Triangulated Mountains image. I just used a bunch of Displacement Modifiers and some Decimate Modifiers in order to get that “low-poly” look. For the outer wire thing I did it a little bit differently. I duplicated the main mesh, then deleted only the faces. I added another Displacement Modifier and scaled it along the normals in order to make it look different and bigger than the original mesh. I then added Icospheres to the vertices using a particle system. After converting the particles into actual objects, I turned the wire mesh into a curve in order to add some thickness by adding a Bevel to it.
For the lighting and rendering, I just added a simple Mix Shader of a Glossy and a Diffuse Shader. I made the color for the Diffuse Shader a blend of a sort of purple and blue based on a Fresnel Value. I just used a big mesh light straight above the object and a curved plane in order to give that “infinite background” effect.
