Some interfaces present the user with a collection of non-overlapping tiles of different sizes. For example:
Similar layouts include Pinterest and Windows 8 / Xbox, but looking at screenshots these are more regular - they seem to define global columns or rows but there are none enforced in my visual example above. I'm thinking more Packery than Masonry (unless the same term applies to both and it's just a matter of degree).
Is there in fact a name for this layout?
