Ever since Grace Hopper came up with the A language programmers have been trying to create new languages and processes that make it easier to do work with computers. This has led to a constant flow of new ideas, syntaxes and programs that purport to make our lives as programmers better and easier.
Now that WatchOS 2.0 is released we have more than just frame animations in the SDK. It now has animation support for moving things around on-screen. It's not terribly powerful because it is based on their layout engine. The layout engine organizes content by Group, Image and Alignment. If it were D&D alignment it would be Lawful Neutral, which doesn't sound fun, but it's not even that much fun; it's alignment to a parent element (left, right, top, bottom). Many properties are animatable, though, including alignment, width/height, background color/image, color and tint color.
