Confirmation

[pogodragon]

You know you're in the right class when, at the end of the lecture the lecturer puts up an image, which admittedly did link, if a little tenuously, to the subject under discussion just because he loves the image so much and had to fit it in to the class somehow. Then, after the official end of the session when I mention that one of the figures in it *will* be giving me nightmares for a while he compares it to 'That Dr Who episode'

Edit - 'cos I suspect someone will want to see what I mean.
This is the general view.

And this is the one that will be haunting me for a while (the one on the right).
