I draw stuff. That's, on a basic level, my job. OK it gets a bit more complex than that and if you fancy a coffee I'll buy you one and tell you about it sometime. But I draw when figuring out a way of communicating information or when actually illustrating technical concepts.
Lines of Enquiry at Kettle's Yard in Cambridge:

Beautiful illustrations of boffins of all sorts thinking through their highly complex work through drawing. Fantastic! Not only an insight into how non-'designers' (graphic) illustrate concepts but just plain beautiful too. This aesthetic beauty was largely a by-product, but sometimes intended (as in the illustrations by Dick Powell and Richard Seymour).
