I am a frequent visitor of TheDieline: The Leading Package Design Blog. The author, Andrew Gibbs, keeps the blog up-to-date, sometimes posting multiple times a day. It is amazing source of inspiration for not only packaging, but the newest and most innovative things going on in design.
One thing I've noticed is that some of the most innovative packages can be found in the alcohol industry, more specifically vodka. This packaging is absolutely gorgeous; I just can't keep from staring.
