When surfing to a finance website, the user sees nothing, where usually commercial banners would appear. When the computer mouse is moved, words from “cold”, “warm” up to “hot” appear in that space. At the same time, the background colour changes from neutral to orange (the branding colour of the bank, Cortal Consors, who bought the banner space, and also a colour that has a very warm appearance). When the mouse reaches “hot” spaces, the regular Banners for the bank appear. The first textlook says something similar to “Trading is hot” in German.
