Lighting, Bounce and Drag Demo – Director (2001). Director-based Lingo demonstration featuring gradient-filled vector circles bouncing autonomously within a defined area. Objects can be manually repositioned using the "Grab" toggle. Additional visual modes include automatic color transitions and continual orientation toward cursor position. The use of gradient fills creates an interactive lighting illusion, with objects visually responding as if lit by the cursor. This visual approach reappeared in later interface components such as CMButton/GlossButton.
