Mobile Understitial


The mobile understitial lets the user look through a gap in the content which reveals a large-scale customer visualisation. It is a relatively discreet AdSpecial, which can easily be realized and delivered by simple material requirements. Due to a parallax effect and a sense of optical depth, it still has an attention-grabbing AdSpecial character.
