Lumina:
A Software Tool for Fostering Creativity in Designing Chinese Shadow Puppet

Shadow puppetry, a culturally rich storytelling art, faces challenges transitioning to the digital realm. Creators in the early design phase struggle with crafting intricate patterns, textures, and basic animations while adhering to stylistic conventions - hindering creativity, especially for novices. This paper presents Lumina, a tool to facilitate the early Chinese shadow puppet design stage. Lumina provides contour templates, animations, scene editing tools, and machine-generated traditional puppet patterns. These features liberate creators from tedious tasks, allowing focus on the creative process. Developed based on a formative study with puppet creators, the web-based Lumina enables wide dissemination. An evaluation with 18 participants demonstrated Lumina's effectiveness and ease of use, with participants successfully creating designs spanning traditional themes to contemporary and science-fiction concepts.
