How much wood can a wood chopper chop...

...if a wood chopper could chop wood?

Taken at Sandford Lock, Sandford on Thames, Oxfordshire during my lunch hour. I hadn't noticed this...er...wood chopping...er...thingy before. I think that it makes for a quite attractive image. The composition isn't quite what I would've liked as there was a weeping willow tree waving its saggy branches and getting in the way. I thought that it was maybe taking a bit of liberty to have gone in an trimmed the branches away.

Is it called a saw horse or something?
