“The Appy Hour program at SIGGRAPH has always been a showcase of the incredible range of mobile applications, and 2021 is no exception. Innovative approaches to animation, photo editing, and even a new take on selfies are all part of this year’s program. I am excited to hear more about these, and others, at this summer’s conference!”
