E-sports music, arts with disabilities, and sand painting represent three distinctive arts, once considered 'unconventional,' they are increasingly valued for their significances and influences as social progress and evolving beliefs. These unique artistic expressions transcend traditional boundaries, offering fresh experiences and perspectives while showcasing unique creativity and talent. Echoes of Diversity integrates e-sports music, inclusive performance of Chinese and Western music, and sand painting, blending theatrical elements with cross-boundary collaboration, it challenges the perception of 'unconventional' arts, conveying messages of unity and inclusion. With its innovative approach, the project aims to inspire audiences to embrace and understand the diversity and different abilities, fostering greater inclusivity within the arts sector and community.
