The first aerial machine created by Chiggio was Quadrati spatial, a series of concentric squares made of wooden strips, presented in the Chiggio/Landi exhibition series in 1961, at Studio N in Via S. Pietro in Padua.There are many variations of spatial squares and, in the 2000s, Chiggio continued his research with new variants. suspended configurations, which conceptually resemble the solids of the Renaissance. Aeromach platonic BR, in fact, is the succession of a series of polygons (square > dodecahedron) that gradually increase their sides extending into space. The research on aerial machines, as well as that on concentric rings and spatial squares, has always seduced the author, as well as everything that moves in space, with all the intrinsic playful component that accompanies it.

Platonic Aeromach BR combines the theme of the aerial machine with that of the White/Red scan, another theme dear to Chiggio. The research on the white/red alternation began in 1970 and accompanies the way that underlies all of Chiggio's research until 2020. It is based on an element of contrast, an indicator of attention, a signal of presence or warning that has a regularity that is in some ways antiorganic and anti-naturalistic.

The BR sequences appear as a geometric scan very similar to that used in optical technical instruments such as stakes and alignment rods of soil geodesy. I am a modulator of Gestalt (coherence, proximity, common destiny), an invariant progressive index. The regular white/red pattern of the Aeromach platonica BR creates regular chromatic neighborhoods that, when the object moves, they lose their coherence.
