Lets talk about transitions. Life is full of transitions. Its the computer screen which leaves us without them. One moment we have a web page open, the next it disappears. When we click on something things change and we've grown to accept this. But in life, everything moves from one position to another and every shape that changes always has a transition. If you design websites in flash you will have already realized that a large part of your time lies in just reconciling the various states that ideas (images, words and sounds) exist in. You conceive loading experiences and you envision what happens when the page changes to the next. Those are all essentially, just the transition. Lets keep transitions natural. Lets let them remain casual. But don't let that stop us from creating stuff that is also beautiful, intricate and detailed. Just don't give the viewer a hard time figuring it out. It should just flow.
