A large multilateral project involving 12 countries: four participants and two leaders from each country. The participating countries are Belgium, Denmark, England, Finland, France, Germany, Hungary, Ireland, Norway, Slovakia, Spain and Sweden. All participants are mentally challenged with Williams syndrome, which means that they are both psychologically and physically challenged. The effects can vary between individuals, but social isolation is a common consequence of the disorder. The purpose of this project is that young people with the same disability should get together, try different activities such as dance, music, country presentations and workshops by discovering similarities and differences in their living conditions in all the participating countries.
