The Secret eXCHANGE is an exhibition in South Korea filled with secrets.  The outside of the envelope contains your persona while the inside contains secrets. 

The front of my envelope has a glass of wine with a flower in it, a Harajuku Lovers logo, puzzle piece, a bar code, QR code and TOP SECRET written on it.

The back contains a skull that I got from a postcard at CES, QR code, Authorized Personnel ONLY!, We are watching you right NOW!, Secret File #28756 and Please enter your code. 

I acted like the envelope was for a Secret Agent.  The code is the secret code the Secret Agent must punch in so the envelope can be opened.

What secrets do you have?  Send your secret to the exhibition.  You still have time – they’re accepting submissions until February 19, 2012.
