physics has to be reworked so that it can apply to this very non-physical cartoon world. For example, in Monsters Inc there is a scene where Mike is training Sulley to scare twins in a bunk bed. As Sulley is popping from the top to the bottom, there are several g 's worth of force on his hair! In the animated world, you can do that, because it looks better. These are the sorts of effects that make us love animation. What would you like to be able to do with computer graphics that you cannot do now? One thing that remains a challenge is a simulated human. We have come a long way, but it is hard because our brains are wired to perceive other humans. If the simulated person looks cartoony, we are willing to accept it not being perfect, but as things get more realistic, a part of our brain that responds to people gets involved and then we are very picky about what we see: if things look a little off, they look creepy. That is a challenge, but I think we are almost there. Any advice for today's physics students? I always advise people to do something they really love because you are likely to be better at it and you are going to spend a lot of time doing it, so it should be something you genuinely enjoy. I think it is a mistake to decide "I'm going to go into this even though
