Cathedral Pan (Made in Blender, Rendered on RTX3090)

I've been making pipe organs in various 3D applications, dating back to Caligari trueSpace in 1995. The complexity would be limited by the hardware, and render times were measured in days.
Today, with a reasonably fast CPU and the RTX3090 and Blender 3.0.1, the traditional limitations of having to wait for renders to see what the lighting looks like, have been eliminated. With realtime global illumination and raytracing made possible by over 10,000 processor cores, the creative energy is allowed to flow unimpeded.
Hence, I created a grand pipe organ and started the cathedral construction. Most recent additions are the console, pedal board and bench.
This scene is rendered in ultra HD and took 20 seconds per frame to render.
