Sylvia Lavin started her book Kissing Architecture with the words of Pipilotti Rist whose work in MoMA years ago she described as kissing architecture. It is probably the most exciting book I have read about architectural theory in last few years. I thought about Lavin’s words during Rist’s London exhibition: ‘A kiss puts form into slow and stretchy motion, loosening form’s fixity and relaxing its gestalt unities. Kissing performs topological inversions, renders geometry fluid, relies on the atectonic structural prowess of the tongue, and updates the metric of time.’
