The intelligent brick can be programmed using official software available for Windows and Mac computers, and is downloaded onto the brick via Bluetooth or a USB cable. There are also several unofficial programs and compatible programming languages that have been made to work with the brick, and many books have been written to support this community.
Lego also initiated a robotics line of toys called 'Mindstorms' in 1999, and has continued to expand and update this range ever since. The roots of the product originate from a programmable brick developed at the MIT Media Lab, and the name is taken from a paper by Seymour Papert, a computer scientist and educator who developed the educational theory of constructionism, and whose research was at times funded by the Lego Group.
Copenhagen Airport is a compact airport with two terminals for check-in, but with a common post-security departure and transfer area, thus making transfers very smooth. The airport handles in excess of 25 million passengers a year, which puts it in the same league as Zurich and Vienna. It has also consistently topped the charts for Nordic airports, serving as a European and intercontinental hub for all of them due to its location.
