The typeface that is geometrically impossible

I love a new typeface, and what better than one that is geometrically impossible!
The graphic artist behind 'Frustro' likes to create mind-bending works. Hegedus has applied the Penrose triangle concept to this font, taking the top left and bottom right portion of each character from a 3D typeface and combining them into the impossible as it seems to be facing two different directions.
I piece of art that makes you stop, look and then look again - I like it a lot!
