The Gift Exchange is an integral part of the Gathering 4 Gardner biennial conferences. Gathering participants exchange gifts, papers, puzzles and other interesting artifacts. There are two ways to participate in the Gift Exchange. Participants either prepare ~300 copies of a Physical Exchange item (typically a puzzle, magic trick, artwork, or other physical artifact) or they submit an Article or Paper to the conference Exchange Book.
The G4G Exchange Book is for those who wish to submit papers as their gift and also for those who wish to include descriptions, instructions, solutions, etc. related to their physical gift.
