While browsing the internet I found an art installation at Miami International Airport. This one, called “Harmonic Convergence” - because when it’s art it can’t just be called “Coloured Glass walkway” - there’s no way a name like that would be selected as one of the America’s best art in 2012…
I figured I could replicate this in 3D, so with several photos to go off and some ideas on how to get GI working, off we went. To make it offensive it's a photo of Chicago in the background - first "cityscape" image I saw that would work.
I think it's 90% of the way there, and in short I've run out of time. That last 10% can take 90% of the time. It's also hard to pick how the room acutally acts with the light, some photos the light is solely from the coloured glass, others have addtional lighting.
Room:
Simple shape extruded around. The roof is a gird cloner with a pre extrude tile and some selection tags in order to apply multiple textures. Using the mograph selector and a plain effector I removed tiles for the light fixtures, which are a linear cloner. If I had done more research, and maybe taken a trip to Miami Airport (bit of a commute to check it out) I might have picked up on a few things I missed like the extra bracing, and that the strip under "MIA Mover" test is reflective, not blue.

Window:
Cloners for the win. As I’ve come across with CUBA, cloners on a 45° angle are not fun. Firstly the math is a pain, working with diagonals (√x²+y²) plus a grid cloner has strange numbers, and that only does ½ of them and you have a whole lot of gaps. For the glass I made a grid of 30x30 thew them all into a null, rotated that 45 and then used the selector and a plain effector to remove all the excess. The beams are cylinders and scaled torus’ in a cloner, same trick with the rotation.

The coloured glass uses a shader effector and gradient texture with turbulence and a noise pattern to get the mixed glass result. This sits in the luma channel, then the cloner has a glass texture that looks at the shader for its luminance.
The window grout is a object cloner using the edges of the window glass.
Render
Physical Sky, Physical render, GI, Ambient Occlusion.
Global illumination - using an interior - high defuse depth preset with a bump in saturation and gamma. The light fixtures also contribute to the lighting with a luminance channel and generating GI - that useful illumination tab!
