Flos Taccia
A lamp that looks like a classical column, behaves like an upside-down ceiling fixture and still feels stranger than most lighting designed sixty years later.

Achille and Pier Giacomo Castiglioni designed Taccia in 1962 around a simple inversion: place the reflector and diffuser of a ceiling light on a base and let the light bounce upward. The ribbed aluminum body was originally informed by heat dissipation; the current LED version keeps the form even though the thermal problem has largely disappeared.
The evidence sheet
The mechanism became the ornament
Taccia earns its visual force from parts that explain how it works: the grooved body, oversized bowl and reflector. Nothing needs a logo to announce itself.
Only when the lamp can command the room
The lamp itself is allowed to be one of the room's major objects. At this price, hiding it in a corner defeats the argument.
The catch
You can buy excellent indirect light for a fraction of the money. The premium is primarily the Castiglioni object, not illumination performance.
