   Un mondo visivo solo, e deliberato: la sala di regia. Sempre scuro, perche'
   e' scura la stanza in cui questo software si usa; il verde "segnale" e il
   rosso "tally" non sono decorazioni ma i due colori che in una regia
   significano gia' qualcosa.

   Ogni modulo ha la sua tinta e se la porta dietro ovunque compaia: dalla
   scheda in home alla sua pagina. E' l'unico modo perche' quattro nomi
   diventino quattro cose riconoscibili.
