Sweden Solar System
the world's largest permanent scale model of the Solar System. The Sun is represented by the Ericsson Globe in Stockholm, the largest hemispherical building in the world. The inner planets can also be found in Stockholm but the outer planets are situated northward in other cities along the Baltic Sea. The system was started by Nils Brenning and Gösta Gahm and is on the scale of 1:20 million.

Casalattico - Wikipedia, the free encyclopedia
How wierd. Many of the well-known chippers in Ireland are run by families from the same comune in Italy.
In the late 19th and early 20th century a significant number of young people left Casalattico to work in Ireland, with many founding chip shops there. Most second, third and fourth generation Irish-Italians can trace their lineage back to the municipality, with names such as Magliocco, Fusco, Marconi, Borza, Macari, Rosato and Forte being the most common. Although the Forte family actually originates from the village of Mortale, renamed Mon Forte due to the achievements of the Forte family. It is believed that up to 8,000 Irish-Italians have ancestors from Casalattico. The village is home to an Irish festival every summer to celebrate the many families that moved from there to Ireland.

Tactical Chat: How the U.S. Military Uses IRC to Wage War
Excellent stuff. Lessons to be learned from this: IRC has some key features that mean it can be useful in this case.
1. simple text, everything supports it, no fancy UI clients are necessary;
2. resilient against lossy/transient/low-bandwidth/high-latency networks;
3. standards-compliant and "battle-hardened" (so to speak);
4. open-source/non-proprietary.
Despite the U.S. military’s massive spending each year on advanced communications technology, the use of simple text chat or tactical chat has outpaced other systems to become one of the most popular paths for communicating practical information on the battlefield.  Though the use of text chat by the U.S. military first began in the early 1990s, in recent years tactical chat has evolved into a “primary ‘comms’ path, having supplanted voice communications as the primary means of common operational picture (COP) updating in support of situational awareness.”  An article from January 2012 in the Air Land Sea Bulletin describes the value of tactical chat as an effective and immediate communications method that is highly effective in distributed, intermittent, low bandwidth environments which is particularly important with “large numbers of distributed warfighters” who must “frequently jump onto and off of a network” and coordinate with other coalition partners.  Text chat also provides “persistency in situational understanding between those leaving and those assuming command watch duties” enabling a persistent record of tactical decision making.
A 2006 thesis from the Naval Postgraduate School states that internet relay chat (IRC) is one of the most widely used chat protocols for military command and control (C2).  Software such as mIRC, a Windows-based chat client, or integrated systems in C2 equipment are used primarily in tactical conditions though efforts are underway to upgrade systems to newer protocols.
