When we visited that room in 2012 or so the walls on the other 3 sides had Picasso's studies for the final painting.
The combination of those in proper size context to the astounding thing on that wall was... I dunno, very hard to bear? Chills and goosebumps. Just being in the presence of such genius. [Edited to add: I forgot! Many of the studies are clearly over complicated and colorful. And then you turn to see what was the final result. IMHO It's the same with genius software, in a different medium. Prose too, but maybe that's more contentious.]
There is no digital screen representation that can remotely approximate the psychic impact physical proximity to genius creates. I've felt this with many other greats as well.
I've sat alone in 3 different Rothko rooms. Damn. It's all I can say. You have to do it yourself. Tip: pan your eyes slowly while sitting in different corners.
