New Projects

Animāre

Animāre (pronounced ah-nee-MAH-ray) comes from the Latin "to give life," which is also the root of the word "animation." This project sets anime creation as a key application domain to develop foundational techniques for malleable tools and realize an environment where anime creators and tool developers can form reciprocal relationships.
