Bird Feeder?

Oo-er! What is it? Well ... er ... hem ... it's a circular cage full of rocks. It could be a giant bird feeder. Whatever it is, it stands near Gants Hill Underground Station (on the Central Line, in case you have an overwhelming urge to gawk at the thing). And ... wait for it ... it's a work of public art! Wham! Zap! Poweeee! Yup, folks, this is the sort of litter which tax-payers' money is squandered on when it falls into the hands of arty twerps determined to enhance our environment, whether we like it or not. Wouldn't a tree have looked a lot better? A rowan, perhaps, covered in bright red berries at this time of year. That would have been worth looking at. This mess just gives 'art' a bad name.
