I don't like Jonathan Barnbrook's work. I find it too style driven and Ray Gun for my liking. I don't like Adbusters either.
Still, he's a very good graphic designer and he does lots of interesting work. Squeezed behind the Hadid exhibition is an exhibition of his work and I really enjoyed it. It helped that lots of the work was explained better in the 'exhibition' context. Do yourself a favour and make a visit to both exhibitions soon.
There are some more pictures here.
