This is the painted Relay Station / Doomsday Device that I built out of bits and a shaped wooden block that was originally intended as a replacement bed part. A Verdus Prime necron is shown for scale.
I've added three lines of red, green and blue along the surface of the Doomsday Device -- suggestive of external wiring and thrumming power of unknown, arcane origins that may date to the Dark Ages of technology. The rest of the model is painted in black and has boltgun silver highlights and drybrushing across its surface.
I think it wouldn't look out of place on many battlefield surfaces, and personally reminded me of the necron table I played on at a tournament a few years ago.
I'll be using it as a line of sight blocking terrain piece and backdrop.
