Google quietly added Google maps for non-US world. Slovenia is also there! Not in very high resolution, but still very interesting.
Some places, like Scotland, Iceland, Kuwait are in hi-res. Thanks, Google! Can we, please, get the regular maps also?

Loška dolina
Via the amazing Google Sightseeing.
Update: Jonas found parts of Slovenia that are hi-res. For example Piran. Hi-res / Low-res border is very obvious. The brown-ish parts of Europe are hi-res.
