These are the slides of the talk I gave as my `valedictory seminar' from the Edinburgh LFCS. It was very nice of them to invite me.
If your browser doesn't do frames (or does them by hanging), you've had it, I'm afraid. You see, in the pages which follow, the pictures appear in a frame on the left of the window, whilst the commentary, such as it is, appears on the right, together with the navigation links. Links within the main body of the commentary advance the accompanying image appropriately. Any supplementary references can be found at the end.
While you're reading this, your browser, unless it's too clever by half, has started loading the images for the first few slides. In fact, it should be loading the images for the whole talk. That's what the dots at the bottom lead to. If you're on a fast line, don't bother waiting. Otherwise, it might be a good idea to have a cup of tea, or whatever takes 2Mb-odd time, and let your cache fill up with my silly cartoons.
