There ought to be some law decreeing that large works of abstract art in public spaces should have an easy-to-find plaque close by, explaining what the artwork is and who made it. I had to look it up when I got home: apparently, it's called "Infinite Accumulation" and was created by Yayoi Kusama, who was commissioned to create it as part of the Crossrail project that resulted in the Elizabeth Line (or the Lizzie Line, as I like to call it).
According to Kusama, "The spheres symbolise unique personalities while the supporting curvilinear lines allow us to imagine an underpinning social structure".
Yes, right. This would be the same Yayoi Kusama whose artwork began to feature polka dots in 1939 when she was aged 10. Those are basically polka dots in 3D.
Now we have large language models at our disposal, it's much easier for artists to concoct an explanation of what their works mean.
I want easy-to-find plaques!
