Stefano Tonchi is reminded of a Yayoi Kusama rogue exhibit at the Venice Biennale many years ago in 1966:

when, with the help of the Milanese artist Lucio Fontana, she presented “Narcissus Garden,” a rogue installation of 1,500 reflective metal balls. (At the time, Kusama, dressed in a kimono, hawked the balls herself for $2 a piece on the lawn in front of the Padiglione Italia in the Venice Biennale Giardini.) Another version of the same work is now in Milan and it still leaves you breathless, letting you see your image reflected endlessly on the spherical surfaces. The effect was even more dramatic at night, when the images were reflected not just on the balls but on the glass wall facing the garden behind them.
