An interesting cluster of services at Schiphol airport near Amsterdam. This meeting point is enriched with:

A physical whiteboard so that people can leave messages, notes and writes stuff.
A dual screen that: (a) explains how to send SMS messages, (b) list the different messages that people sent with their mobile phone. You can send messages to greet people and tell them you're arriving (or simply to take a certain transport mean).

Why do I blog this? It's interesting that both media (physical and electronical whiteboard) are present. Each of them have their own values (the physical one is available in case of power failure or if the tv screen is our of order) and allows a sort of presence mediated by different characteristics of the artifacts employed.

I also find relevant to observe how cluster of services are deployed in physical space, see also here.
