|Another of the books in the series|
It's a rather fun idea from my UK publisher Icon. They produce the pocket-sized 'Introducing, a graphic guide' books, which combine punchy text with artist-created illustrations. You can see the kind of thing in this sneak peak of Introducing Relativity, though I have to say that the illustrations in the new book are much crisper and better drawn than these appear to be in the sample. Icon is running a competition to get a cameo role by being drawn in a new book by a well known popular science author (ahem), Introducing Infinity. So the winner will have themselves drawn as one of the figures in an image illustrating one of the pages.
To enter all you have to do is summarize a topic that the Introducing series covers in 100 characters in a tweet which contains both the hashtag #beinabook and the link http://tinyurl.com/bpal8od (that's just a link to their competition page). Simples, as all the best meerkats say. The closing date is 5pm GMT on Thursday 5th January 2012. The winner (judged most amusing and accurate by Icon Editorial Director Duncan Heath and me - sadly bribes are not allowed) appears in the book, while the 25 runners up get a free copy of an Introducing book.
That should be enough to enter, but to find out more see Icon's page on the competition, and to see the range of topics, here's a list of their books.
