After being assigned a traveler back-pack, my concept was pretty much established. After starting to rip off the black outer fabric, I found a shiny mint-colored lining and green inner zippers. The inspiration was the act of discovering more and more, in other words, crescendo poco a poco.

The idea of crescendo is later accentuated on the gradual experimental floor tilt.  That is why the second floor acts as a climbing platform to find the hidden underlining program, just like the lining of the bag.
