Twitter Ticker Tape

I got a day on my own - the others had the tickets for Wimbledon. So, I went for the newly opened Spy exhibit at the Science Museum. 
Very interesting. Especially the other enigma machine, which had 12 rotors, unlike the more famous one which had only 3. I think it was only declassified in the 90's. 

This blip is of an artist's interpretation of data from twitter, where lookups are done and the tweets are printed to receipt paper. So, for all you know, your tweet may have been captured here and printed on one of the many paper streams. 
Although this blip does not show it there was essentially a bin of paper below which you could pick up and read some of the stuff that was printed. 
Quite interesting usage of Twitter and the bile it generates.
