HoloWine projects holographic wine tags to help you navigate your wine cellar. Download free tags from http://holo.wine and use the HoloWine phone app to read the tags.
1) First scan the wine tag with your phone and you will see a default image and be able to "update" the label.
2) Then take a picture of the label and the next time you scan the tag you will see the label.
When you can see the label without pulling out the bottle you get several benefits:
1) It is faster to look for a particular bottle.
2) The wine can rest undisturbed protecting your investment.
3) Glass cellar doors can be kept closed.
