The pictures in this page represent certain mathematical objects, generically referred to as attractors: first, by their own mathematical interest (and by the beauty of some of them); secondly, because the name attractor is associated to our project and is an indirect (and mathematical) way of advertising the project...

The following is a graphical representation of part of an orbit associated to a famous "strange" attractor - the Lorenz Attractor. (The picture was made in 2001 with mathematica and the help of the excellent package of J.-P.Kuska)

A completely different example is the

Sierpinski Attractor

Translated for Atractor by a CMUC team, from its original version in Portuguese. Atractor is grateful for this cooperation.
