Trompe-l'oeil takes affect

A modern take on those German style fake towns that have trompe l'oeil windows and doors that just look so real. Well now some inspired people have come up with complex optics to mimic the way the sun refracts through standard glass in particular situations. This could be a great architectural design feature, with the added benefits like those winter sunshine lamps are supposed to provide.

Or maybe it turns out to be more closely resembling wallpapers that show countryside views or lakes, cheap tat that does nothing for body or soul. There's some interesting articles on the graphics of design just for fun. Look forward to seeing it for real (sic) sometime soon. Brilliant idea!
