Inner Message Ring
St. Valentine's Day is approaching, and while this may not arrive in time for the holiday, isn't every day special when it's with your sweetheart? </sappy>
The Inner Message ring leaves an imprint on your finger after you have worn it, and the designer appears to be taking custom message orders. I have to say this is a great example of design directly interacting with the user. I don't know how long it takes for the impression to appear, however, or if it would be painful, but I do like the idea.
