The Four Towers and street art.

Many thanks, Fred!

I wondered something while looking at your other shot of the four towers. When multiple buildings of nearly the same height, shape and width are built side by side, how vertically off-level does one or two have to be so that it's noticeable by the naked eye? Of course, the one second to the right would be misleading due to its angles.

Yes, graffiti...okay, street art... is like cockroaches. (Well, technically, that would be ARE.)

Despite the above irrelevancies, that is an amusing shot

... and I just have time to reply before I tootle off to my first class of the day!
It is interesting (to me at any rate) that I have only ever taken shots from this angle. I've never been in a position to take shots that show how different they look from elsewhere in Madrid. Firstly, you are quite right, they are not all in a line but slightly out of kilter with each other and there is a larger gap between the middle two where there was to have been a taller, central tower.

Secondly, the only one which is as broad as it is wide is the pencil shaped one; the others look fuller from different povs and the one one on the right positively bulges out at the bottom, swelling along the line of the curve you can see. I might take the bus to the other side and look for a shot to illustrate these points. With fewer classes in the summer, I have the opportunity!

And thirdly, graffiti, mainly illegal, has been with you and us since the early 70s (maybe earlier in the New York subway) and I still dislike it intensely, in the main. But this lot is technically good, officially sponsored and does cheer up an otherwise hideous site that I have endured many times a week for 7 years and it has made a difference to my state of mind on arrival at a class in one of these towers or when returning to the station.

Glad you found the shot amusing!
Off to work!!

Alright, then, this is a case of street art! ;-b
