(*) This work was done in Atractor in the framework of a grant attributed by the Fundação para a Ciência e a Tecnologia.
Since many browsers are blocking Java nowadays, it was decided (in 2021) to convert to Javascript the original applets of this section. This conversion was carried out by a high-school teacher, who is working full-time in Atractor with the support of the Ministry of Education.
