Customs are a form of social regulation. Love them or loath them customs allow us to form connections, to find a sense of stability and order, to differentiate ourselves from others, align ourselves with others, and not least enjoy regular festivities and parties as customs are celebrated and/or enacted.
Customs are therefore inherently good.
Unless it is the sort of Customs which sit at the border between two counties and stop a young Swiss ceramicist displaying their work at an international design festival.
That's a bad custom(s)
At which point we'd like to hastily we add we have no information as to the background to the problem and attach no blame for the non-appearance of any works in any respect to the customs officials involved.
But still. Boo!
We've not seen Klein's Lamp by Lucien Dubuis, however our innate sense of fair play and solidarity leads us to say that it is a series of enamel LED lamps created by Lucien Dubuis from the Atelier Poterie de Gruyére in Bulle, Switzerland, and is inspired by the so-called Klein's bottle: a non-orientable surface described by the German mathematician Felix Klein in 1882. Essentially formed from the fusion of two Möbius loops Klein's bottle is a vesicle who's inside is also its outside. Impractical for carrying fluids, but perfectly suitable as a lamp.
We'll have more to say should we ever get the chance to view Klein's Lamp by Lucien Dubuis.
An event which we assume, should it happen, will happen in Switzerland.
