...because for 4 days there is a modern city of Babylon...

...and it is called the GSMA Mobile World Conference. Last week it was here, 60000 people from around the world come to learn, share, buy and sell mobile stuff.  Walking around it and hearing so many languages was like being in a modern city of Babylon -interpretation assisted by wifi and mobile phones! 
And this - a very cool music making machine!
