Core Escher is a beautiful font family based on the work of M.C. Escher, an artist who specialized in optical illusion art.
With rounded shapes and layers, this typeface perfectly recreates the impossible perspectives that Escher often pictured with strange stairs or castles.
With the sub-families offered, you can create different viewpoints to change the optical illusion, making the typeface much more efficient in every situation. You can buy this font on MyFonts.
