All around the world science museums and science centres are experiencing a strong growth. At the same time more and more research institutes develop exhibitions as a major tool to communicate current research, and visitor centres are created everywhere to help citizens engage with natural and historical heritage.

In the majority of cases architects, 3D designers, multimedia developers, content developers, etc. learn their jobs on the ground.
