Like this interaction

Recently I've seen quite a few, text in interaction installations, there was one in america, a text in to interact with a game on a massive advertising screen, a more simple version, is this one in well I think its germany, the website is in another language, of course I could use a program to translate it, but the jist of the idea is clear, using your mobile you can change the colours within the installation/ building. Though it does look like its in a stark place, where no one would see?

They really should introduce some interactions in London, though I'm afraid they are already cutting costs at christmas, will they spend money on such things? Though London is great for odd delights, but would be great for some more interactive elements in the capital, even if they are movable/temporary.
