A semi-accurate reproduction of the clock I have by my computer.
I say semi-accurate as I tried to replicate the look and feel of the tubes rather than their exact internal structure, also my clock has no actual base apart from two lego pieces so I made up a base for this model.
Done completely in Blender 3D, cycles render and all (cursed the lack of accurate caustics.)
All procedurally textured, nearly ended up using Substance Painter but Procedural Pro had all I needed.
