Luis Martín, an artist from Murcia, plans to create “a huge 15-metre-wide sphere of cultural brotherhood”, which will be filled with 100 litres of donated semen. He started collecting the sperm last Sunday on the La Cañada beach in Almería. He told reporters he has had no problems with the authorities so far, and is looking for sponsors so that donations can be collected all over the world. He said donors have to be over 18 and that once collected, the sperm will be kept in a fridge. He said he hoped that the sphere will eventually be displayed in the Reina Sofia or Thyssen Museums in Madrid. The museums have not made any comment as yet.
