Oh, Not Gallery (a Beijing-based art institution specializing in the promotional art of public spaces) and ISPVA(The International Society for Performing and Visual Arts) present the first major virtual exhibition, X-Hale, with a series of live streaming conversations between artists and audience worldwide. This visual design project includes promotional materials like logo, posters, banner, trailer design, and graphic assets for live streaming. The pandemic brought drastic changes in people's lives. As everyone is exploring their ways to cope with the unprecedented situation, new and creative ideas sprung up too. The primary subject is a 2.5D structure, and the designer used Iridescent color to present a sense of lightness, fluidity, and mystery.
