"We have assembled objects in the form of a human figure, objects of all types that we found here each day and selected for their form and color, to obtain a familial nucleus that is the unity through which the individual forms itself and develops its ability to live and realize itself in the world." Artworks by Dario Tironi. via iGNANT
"The Szpilman Award is awarded to works that exist only for a moment or a short period of time. The purpose of the award is to promote such works whose forms consist of ephemeral situations." This years winner is Treebute to Yogya. The organisers also maintain a blog and an encyclopædia of ephemeral works.
