Samantha does an excellent job of explaining how useful style tiles can be for visual design and iteration.
Samantha put together this handy one-page site to explain Style Tiles as part of her South by Southwest presentation.
Samantha gives the rundown of a hands-on use of Style Tiles.
An excellent design technique from Samantha that allows you to nail down a visual vocabulary without using something as wishy-washy as a mood board or as rigid as a fully-blown comp. Brilliant!
The style tile is not a literal translation of what the website is going to be, but a starting point for the designer and the client to have a conversation and establish a common visual language.
