"Designed by Oliver Rokison a teacher at St Paul's School. This project connects to the Tower Bridge twitter account and mimics the movements of the real tower bridge." Fun.

"The Tower of London tweets every time it opens and shuts..." Nice sub-editing, Daily Mail!

"The city is here for me to use, and it tells me so." Indeed.

"sometimes we geeks forget about all the delightful and beautiful things we can build. The things that aren’t necessarily useful or purposeful, but pointless, silly and wonderful." Tom on fire with lots of lovely examples.

"That’s why I enjoy @towerbridge so much - less the concept of machines talking, but more a simple reminder of the disrupted moments in everyday city life." All this is also true. Beautifully put, by Tom.
