For the boring but important hyperlinks on my site I wanted a special button instead of the typical icons you see everyday. I like buttons (the physical objects) very much, and I thought Why not have a literal take on the idea of a button? If people are clicking on buttons, why not make them actual buttons?
Created in Adobe Illustrator, I applied the craquelure (it creates cracks) and plastic wrap effects. I added a darker grey to the outside rim to make it pop a little, as well as on the holes to create depth of field.
