Ah shoot, that’s a good catch. Sorry that wasn’t clear. I was intending for all of this to make it into the live product. I use marketing because that was always the point at which I realized what I designed doesn’t show well. Another thing I should’ve pointed out is that I think there’s a lot of benefit to doing this for usability because it helps users learn new concepts. In my “Add cards” I think the final product invites people to read, while also making a brand impression on users.

Looking at dribbble you can find a lot of other visual treatments that should never make it into product (extremely broad shadows for example). I tried to keep these examples limited to methods that would be marketable and usable.
