The first few bags build the small truck with carts that you see on airport runways. The truck has a "follow me" sign that I confess I have not seen at any airport. There is also a fueling tank and a rolling staircase that sits next to the plane to allow for boarding. Both the tank and the staircase are additional carts for the truck, though I am guessing not both at the same time.
The remainder of the build is the control tower and terminal building. First there is a metal detector screener leading to the waiting/secure area of the airport, which seems taller than it needs to be for the minifigures. I think the same effect could have been made with half the height, except that would not allow for an impressive height for the overall tower. However it does seem to be similar to many modern airports with the high ceilings. This area also seems to be someplace to check luggage as evidenced by the rather nifty conveyor belt that comes in a full part. The moving parts of the set include a revolving door (a very tall one, for the first floor) that leads from the secure area of the airport out to the tarmac, and of course the conveyor belt.
Even in terms of play value it mostly seems to be a trade-off — 60104 loses the vending machine, cafe, baggage x-ray scanner, and a few seats on the plane but gains a baggage conveyor, a restroom, a refueling tank for the plane, an additional minifigure, and more seats in the waiting area. It's pretty nice to see the value of a LEGO air terminal remain fairly stable even though the price has not increased.
City has had many games since it was released. One in particular, The Robot Chronicles, was a cross-over game which saw the City, Racers, and Agents 2.0 all together in Lego City, where the player controlled and unlocked vehicles in each theme to play through a campaign. This campaign/game was also tied into a My LEGO Network The Robot Chronicles campaign- playing the game earned rewards in MLN which could be used in that campaign to eventually get the Key to LEGO City.
LIC - LEGO Instruction Creator, developed by Jeremy Czajkowski, is a cross-platform, Python, OpenGL & Qt powered desktop application for creating and editing LEGO instruction books. LIC imports 3D models, organizes them into submodels, pages & steps, and exports the end result as images or PDF. A rich, WYSIWYG UI editor, which provides a fully interactive preview window along side a drag & drop-enabled navigation tree, to help organize and layout your book. Portions of LIC are based on work of Remi Gagne. LIC will be part of the AIOI - LDraw All-In-One-Installer.
In December 2012, the BBC's More or Less radio program asked the Open University's engineering department to determine "how many Lego bricks, stacked one on top of the other, it would take for the weight to destroy the bottom brick?" Using a hydraulic testing machine, the engineering department determined the average maximum force a 2×2 Lego brick can stand is 4,240 newtons; since an average 2×2 Lego brick has a mass of 1.152 grams (0.0406 oz), according to their calculations it would take a stack of 375,000 bricks to cause the bottom brick to collapse, which represents a stack 3,591 metres (11,781 ft) in height.
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.
