Antony Gormley's 'One & Other'

Not been much on the fourth plinth in Trafalgar Square to interest me or anything at all really since this Antony Gormley 'installation' or whatever you want to call it started but last Sunday there was a naked man (he's not the first and there was another just a few days later).
All very titillating and certainly entertaining for the tourists on the open top buses going by but is it art?
I'm a big fan of Antony Gormley's work but this, well maybe I'm not getting it because I just can't find anything to appreciate. If the object was to perplex then it has succeeded but I think there are far better reactions to illicit.
Oh and apparently it's not a crime to be naked in public according to this BBC story which confuses me as an earlier exhibitionist on the plinth was made to cover up.
Postscript: I've had to take the slide down as someone complained to Flickr but here is a still. If you are offended by nudity look away now.
