Last year I wrote about why booking too far in advance can be dangerous for your business, and this concept of margin so eloquently captures what I had recognized had been my problem: I was so booked up with clients

Because the topic of motion in user interfaces is mostly understood by designers to be ‘UI Animation’—which it is not — I feel like I need to create a bit of context before we jump into the 12 Principles.‘UI Animation’ is typically thought of by designers as something that makes the user experience more delightful, but overall doesn’t add much value. Thus, UI Animation is often treated like the red-headed stepchild of UX (apologies to red-headed stepchildren everywhere). If at all, it usually comes at the end, as a final lipstick pass.The act of masking asking can be thought of as a relationship between the shape of the object and it’s utility.Because designers are familiar with ‘masking’ in the context of static design, it behooves us to bring distinction to the UX in Motion Principle ‘Masking’ as it occurs in time, as an act, and not as a state.Through the temporal use of revealing and concealing regions of an object, utility transitions in a continuous and seamless way. This also has the effect of preserving narrative flow.

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of “de Finibus Bonorum et Malorum” (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, “Lorem ipsum dolor sit amet..”, comes from a line in section 1.10.32The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from “de Finibus Bonorum et Malorum” by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham.There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don’t look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn’t anything embarrassing hidden in the middle of text. All the Lorem Ipsum generators on the Internet tend to repeat predefined chunks as necessary, making this the first true generator on the Internet. It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which looks reasonable. The generated Lorem Ipsum is therefore always free from repetition, injected humour, or non-characteristic words etc.
