For some time my newspaper of choice (The Guardian)has been giving out wallcharts depicting different varieties of things. It started with things like fossils and animals, but they seem to have been running out of steam recently, having to resort to footling things like apples and salad vegatables to keep going.
Tomorrow they are giving away a cheese wallchart. Oh yes. One for the office wall methinks.
Note: I know that cheese is essentially a lump of fat with good PR, but I still like it.
