Explain

Alice uses drag-and-drop blocks to create 3D animations and scenes.

Programs are built by controlling 3D objects, characters, and camera views.

Ideal for learning logic, events, object-oriented thinking, and storytelling.

Frequently used in schools for CS introduction.

Helps transition students to text languages like Java or Python.
