I can remember my mum telling me to let go of my joystick and go outside and play 'normally' with other people my age  - I kept telling her that 30 year olds tend not to play outside anymore, but she had moved on by then - and even though I could see her point I always wished that there was some way to combine the two.

Well, apparently there is. Some industrious gamers/vandals have created their own "building-sized" game of Tetris with which to amuse themselves.

Of course, it probably only amused them for ten minutes, but I am sure it was worth it.
