In A rather off-topic post for this blog, the long-awaited answer to what a Jawa actually looks like can be answered. In the iTunes version of Star Wars Episode IV, the Cantina Rough Cut deleted scene shows a regular Jawa with a partially-unhooded Jawa at about 1:02 into the scene.
After seeing this, I can't help but wonder if we'll be seeing more Jawas. They're much cooler-looking than I'd imagined. Have you seen this scene yet? What do you think?
