The final product is a set of three "trees" consisting of a branch with wires on them attached to the stairwell. People walking past can pick up a notecard, write something on it with marker, and hang it on one of the wires. This causes the wire to bend down. The branches are attached to the railing posts with tape, but it is covered up with paper to look more natural. There is also a speaker nearby that plays forest sounds.
Is this a good/useful/informative piece of content to include in the project? Have your say!
