The "Ghost" project is an art project featuring 69 different artworks, which will be available for purchase through a ranked auction. One artwork is revealed each day over the course of 69 days. The project is called "Ghost" because the identity of each artwork is not revealed until it is unveiled on its designated day. Those who participate in the auction can place bids on the artworks, and the final price for each piece will be determined by the lowest winning bid. Any excess funds that are paid by the winning bidder will be refunded to them. Those who are patient and follow the project from start to finish will also be rewarded with a gift at the end of the 69 days.
