Was rather impressed by this Artist in a local shopping mall (Abbeycentre). The image looked distorted until viewed from a particular angle where it came to life in 3d!
It was an anamorphic image of half dead characters trying to climb out of a pit with skeletons in it, at the side he had a real rope tied round a pole extending from the chalk drawing on the floor. Rather creepy when viewed from the viewer they had set up!
It's clever stuff and I like the way he takes the very mundane - rubbish chalk drawings on pavements - and makes it something special. I don't think he's a wonderful artist in absolute terms - they're not brilliantly technically executed - but the work is engaging and people talk about it, so the work succeeds on that level.
