V-Jam mood maps
Oh yes, I forgot. (I twittered about this yesterday but not much space to describe it)
In one session we had lots of fun with a simple, but not very realistic idea.
Every seatback terminal has a mood selector. Where you can set your mood: Tired, Hungry, Irritable, Happy, Calm, Perky, etc etc ...whatever.
The resulting colour-coded digital map on the bulkhead or in the galley (for the benefit of Cabin Attendents) would be great fun. :)
Imagine the solitary green guy who finds himself sat in the middle of a miserable all red section!
