The logo of the conference is a K-dron, an eleven-sided spatial form discovered by Janusz Kapusta in 1985. The name comes from dron which is Greek for “wall”, and k is the eleventh letter of the Latin alphabet.

The spatial form was invented during the preparations for an exhibition by Mr Kapusta and one of his colleagues in one of New York’s galleries. After printing the promotional leaflets, containing an image of 2 inscribed squares, Janusz Kapusta came up with a spatial form which resulted in him producing its model.

The K-dron is made up of a k-dron plain which is a rhombus with rectangle triangles attached and the base of a K-dron. Two K-drons put together form a cube.

Sets of K-drons may be arranged in various ways which interact well with light and shadow. Changing the angle of incidence will create new shapes.

It’s used to design building elevations, toys, games, jewellery and even hubcaps. There are many applications of this spatial form – Janusz Kapusta described 50 in his book, and in April 2001 he spoke of finding 168 already.
