+# The World is Your Canvas: Painting Promptable Events with Reference Images, Trajectories, and Text
+
+WorldCanvas is an I2V framework for promptable world events that enables rich, user-directed simulation by combining text, trajectories, and reference images. It allows for the generation of coherent, controllable events that include multi-agent interactions, object entry/exit, reference-guided appearance, and counterintuitive events.
