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.[51]
Compared to other major European hub airports, like Charles de Gaulle or Heathrow, CPH has a similar number of connections, but is much smaller in both actual size and passenger volumes, and can provide a calmer, more pleasant experience. Its location in the south of Scandinavia makes reaching most European destinations reasonable, and flying to destinations in the Baltic region and in Eastern Europe generally only takes half the time as from major hub airports in Western Europe.
The last of the three aircraft is a modern biplane. This incorporates a number of rare orange elements including right and left 8 x 3 wedge plates which make up the wings and have only previously appeared in three sets, a 3 x 4 wedge brick only previously found in two sets, and a 3 x 6 round half plate with a 1 x 2 cutout which has only previous appeared in a single set in this colour and which forms the tailplanes. Similar to the two jets the tail fin is stickered rather than printed, as are the pair of 1 x 4 x 1 panels making up the sides of the cockpit. Unlike the jets, however, the instrument panel is stickered, which seems odd as there are existing printed 1 x 2 light bluish grey tiles which could have done an acceptable job. There are also a pair of stickers which represent the engine exhausts and which are applied to a couple of modified 2 x 4 x 1 1/3 bricks with curved top which sit just behind the propeller; applying these neatly to the curved surface takes a steady hand, and that’s also the case for the pair of checkerboard stickers which are stuck onto the propeller cowl. As if stickered exhausts weren’t enough, there are also a couple of light bluish grey exhaust pipes with Technic pin which emerge from the propeller cowl and run along either side of the fuselage. They’re entirely superfluous given the presence of the stickered exhausts but they still look cool regardless!
Basically, the only thing that the two sets have in common is that they both have planes. However there is quite a bit of difference on the inside of the planes. There are a lot more details in the Friends plane. In addition to the seats, there is a rolling service cart complete with refreshments, emergency lighting as well as a larger galley and lav in the back of the plane.
Since around 2000, the Lego Group has been promoting "Lego Serious Play", a form of business consultancy fostering creative thinking, in which team members build metaphors of their organizational identities and experiences using Lego bricks. Participants work through imaginary scenarios using visual three-dimensional Lego constructions, imaginatively exploring possibilities in a serious form of play.[73]
