INSIGNIA on Spanish TV!

The INSIGNIA project has drawn the attention of the Spanish TV channel Canal Sur! Two of their reporters visited the lab in Almería and asked some questions about the APIStrips and the project progress. Two days later, a short description of the work performed by the INSIGNIA group was broadcast on the news with a small part of the interviews to the Almería team.
