The first item on my list to research is the concept of Skeumorphism. The best information I could find on this was on the bbd website.
This is very simplistic definition of something that is a theory ingrained in the human condition. We always need to categorise new experiences in accordance with our existing ones in order to fully understand them. This is something that is particularly relevant when looking at new developments in technology and how to operate it. Skeumorphic designs allow instant reference to the users knowledge, to make the operation almost instinctive.
The rise of flat design is the next item on the list. However, after looking into it slightly more I have found that flat design as a concept is a development from skeumorphic design, or a response to it. It almost accepts digital formats as design in their own right, designing for the format in a completely different way because audiences now have a much greater understanding of digital operation than in previous years. the source below explains the relationship between these two ideas quite easily and concisely.
The Adobe Muse website is another one that uses this flowing moving format. However, there is so much movement that it actually makes me feel motion sick. Perhaps the designer got a bit carried away with the moving elements.
