First I worked with red cubes on a black backdrop...the texture is using the 'wax' preset and I edited the subsurface scatter to give it an organic feel. I also began working a bit with depth of field blurring to give it a more dramatic effect. I don't necessarily like working with DOF in a 'destructive' way like this, but I think it gives a nice look...and considering this is quite a raw way of working, I at least don't mind a little bit of graininess (although this is not up to me).
I later also began swapping the colours so the geometry was black and the background was red. I have no animation for this just yet, but I quite like how this looks as well. I also tried out using subdivision to turn the cubes into spheres to see how it looks.
