Hello! I would like to introduce a rather specific type of site navigation and need some help finding a tool to do it. Imagine a doodle of a city landscape with a windmill, a water tower, and a bridge in different semi-transparent colors, each representing different engineering disciplines (electrical, environmental, and civil, respectively). When you hover over the windmill, the color will become opaque, and the word “ELECTRICAL” will show up in the same color to the side. Then, when you click on the windmill, you will be taken to Electrical Engineering page.
Is there anything that comes to mind for such a thing? The idea is to present engineering as an essential and connected part of a society right off the bat.
