Lottery is a web-based raffle program designed for company annual dinner events. It lets an organizer import a list of participants from an Excel spreadsheet, configure prizes and rules, run the raffle live with a visual 3D spinning sphere showing the pool of names, and then export the results back to Excel when the event is over. A hosted demo is available online to try without any setup. The visual display is built with Three.js, a JavaScript library for 3D graphics in the browser. The backend is built with Node.js and Express. During a draw, a 3D sphere spins on screen with participant names or photos displayed on its surface, and winners are selected and announced as it slows to a stop. Configuration is done through a settings file. An organizer can set prize names, the number of winners per prize tier, and the text or images that appear on the sphere. Participant data comes from an imported Excel file, so no manual data entry is required beyond the initial spreadsheet. Getting it running requires Node.js installed on the event host's computer. After downloading the repository and installing dependencies, the organizer starts a local server and opens the application in a browser. The main README is in Chinese, with an English version also provided. The project is intended for local use at a live event rather than deployment as a public web service. The described tech stack is Node.js combined with Express for the server and Three.js for the visual presentation. Prize information, participant data, and the number of allowed winners per prize are all configurable before the event starts.
