Here is fist of my entries (second one is coming soon).
Technical details: 544712 triangles, rendertime 5-7 h (that time is needed for average human to sleep

). No post processing or color correction - render as it is

Inspiration: Some time ago we did few effects for documenal film about Vladimir K. Zworykin (He was a Russian-American inventor, engineer, and pioneer of television technology) and this scene was used as background for presenter. It shows inside of iconoscope (early television camera tube). Scene doesn't pretend for any historical accuracy (wrong radio components for that period of time, there aren't holes for elements in plate etc

) and it's been done for visual purpose only. Main goal of this render is testing of Octane render in hard conditions - lots of complex emitters inside the glass, lots of glossy reflectors and elements, dof. Eventually, I'm very satisfied with results - I couldn't stop myself from taking pictires - that's real "octane magic". Thank you, guys

Big thanks to Vladimir Shelest for initial modeling and texturing. I did some remodeling, additional texturing, materials and rendering.
I recommend you to watch pictures at full screen (on white browser background they look too dark and over contrast)
