Cadàver Exquisit. Artworks created for Exposition, February 2013.
Art steward of the exposition. Cadàver Exquisit was the name given to a compilation of 17 artists who showcased creations combined using the ‘cadavre esquis’ technique used by the Surrealists and also individual pieces related to death.
This is a visual representation of pollen concentration in the air of Barcelona.
Each concentric ellipse represents a plant, from outer to inner: Cupressceae, Corylus, Pinus, Platanus, Parietaria, Quercus, Palmae, Poaceae, Plantago, Chenop.-Amaranth, Asteraceae, Artemisa.
Each 1/12 section of the circle represents a month, and each month is divided into four weeks, so it’s not an accurate representation of the original data wich has 52 weeks instead of 48.
The size of the dots equals the density of the pollen concentration in a scale from 1 to 4 and each inner plant is a 10% smaller in size than the outer one. So a concentration of Artemisa pollen of 4 would be a eleven times 10% smaller than a concentration of 4 from a Cupressceae (5 mm and 1,57 mm).
I’m not good at math so excuse the possible mistakes in the explanation.
