If You Look Closely,

you will find this typeface impossible,

why? when an artist renders three-dimensional objects in two dimensions, they normally give it perspective, so that it appears realistic to the eye. However, since the two-dimensional medium (a computer screen or a canvas) has no depth, you can mess around with the perspective part and play to your hearts content,

seeing this typeface I was immediately reminded of the master of optic 3D/2D effects, M. C.Escher, the typeface was created by Macedonian artist Fleta Selmani to create the font she calls Impossible Type. Letters are three-dimensional, but we see them as two-dimensional, You can purchase and download Impossible Type (upper case, numbers, and punctuation) here, what an amazing typeface.
