For this thematic project I will make use of the telephone as a dying medium for networking,
and belhuizen are some last public resorts for these machines.
We are very much used to actively using the Internet by visiting websites rather than them visiting us.
Now the Internet is calling you, in the belhuis.
Scraping all this information you want or do not want to find
(sources yahoo answers, craigslist, facebook, brandmonitor etc etc)
and letting this information find you.

Example1: "Ring ring"... "Its a shame you don't know what your worth! You've let pathetic guys ruin you! \nYour better than that! \nIs your BEAUTY, your curse!?"
Example2: "Ring ring".... "Just to be clear, I'm not really looking for a bodyguard (that's a lyric from the song haha!) just a friend named Betty."

Howto

• Data-scraping: python with feedparser etc (facebook, craigslist...)
• Mastercontrolprogram.py (state-machine) + PySerial + Arduino >> Phone
• Text-to-Speech: festival, text2wave on commandline with the "American female"
• Phone: Mod-copper-phone with 2 inputs (1 audio, 1 ring) and 1 output (fork)
