Every fall, I teach an extended, semester long class on a neuroscience topic, with enrollment open to the public.
I typically get a poster designed and produced to publicize the class and encourage enrollment.
Format wise, I print up 19"x13" posters, and I also get Signographics in San Francisco to make a 6'x4' banner, so at least 1 version of your file has to be suitable for large format production.
Content-wise, the following text has to appear: the title (The Bard and the Brain), the subtitle (The Neuroscience of Shakespeare), and my name (Thomas Lewis, MD).
Graphically, I'd like an image that somehow combines the idea of neuroscience and the idea of Shakespeare, in a cool and/or playful way.
You can see some of the prior years' art in the attached file.
