This is a visualization of the 1236 exoplanet candidates observed by Kepler.
As you can see, the vast majority of these planets orbit their stars at a distance less than Earth. This is likely due to the relatively short observation period - it is highly probable that many more planets will be found as the duration of study increases.
Two candidates are highlighed: KOI 326.01 and KOI 314.02. Out of all the candidates, those two may have the best chances of satisfying some of the "habitability" criteria astronomers tend to use.
A lot of help in making this video came from Lee Billings - who provided key astronomical advice and included the visualizations in his guest blogger posts at BoingBoing:
