The Tower demo showed off what LucasArts was talking about. It gave the player the ability to toss in A.I. controlled character models at will, letting them fend for themselves as they tumbled through a Price is Right Plinko-style structure. While initially it seemed like a rag-doll physics demonstration, it soon became clear that the A.I. models were actively trying to stop their falls. Reacting to their surroundings without the restrictions of pre-programmed animations, the models reached out to whatever beams happened to be closest. Since they were falling at relatively significant speeds, they often missed, but would try again when they passed by the next plank or beam.
Eventually, as they slowed themselves with attempts to grab on, they'd be successful. However, the exercise didn't end there. Some prevailed in pulling themselves up to a standing position, but others lost their grip and continued to fall. The demo achieved an even greater level of complexity when several models were thrown into each other. A hanging model hit by another wouldn't just hang there stupidly while the other ricochets off. Instead, it'll actually reach out its hand to grab the other. In the same way, the tossed model will reach out its hand to try and grab onto the hanging one's leg. As further proof of the advanced A.I. at work, the hanging model would even reach down and try to pull the other up to safety. Most of the time this resulted in both models tumbling down, though at others they would manage to help each other up to safety.
