These are four photos of the steel balloons near the AIIMS flyover. Their utility and futility has certainly been debated in the media. According to a Tribune report, even the CM Shiela Dixit was not very happy with them. I shot them from the bus yesterday en route to the Delhi book fair.
They are called by various names: metallic lollipops, steel balloons, sprouts, mushrooms! I do not like them: they irritate and distract.
One of the tag lines on the Jindal Steel website is this: A whole new world of steel brought to you by Jindal! Yes, indeed as is clearly visible here LOL!
