Solid Wood + Epoxy Resin | Bars Color Representation

I was asked to do some renders with blanks, to make a color representation.
Technical stuff: Blender Rpr, 1000x1000 images, rendered as a frame by frame animation with "epoxy" material color keying. Oh, this is so powerful! What a relief just to be able to do anything but looking at the screen while all the things are doing by its own...
Also PureRef is capable of making collages. Huge collages!
Sorry for the watermark, but its mandatory. Just imagine the content without it... This is how it works, right?
