In-Mouth Sculpture 

 I wouldn't say that this cycle is "inspired" by the greeting habits of the comrades from the vanished kingdoms.

The conceptual framework of the piece is phenomonology of tactility. Rolling something in your mouth based on a visual model, be it a sphere, a disk, a cube or any other Platonic Solid. After your tongue and gums "recognize" the shape as completed it is time to pass it over for an appreciation.

The receptor (apreciator) of the artwork must appreciate it hapticaly, not optically, so the most direct way to pass it over is by mouth-to-mouth transfer.
. Given that the receptor of an artwork is familiar with spatial models (sphere, cube and etc.) the aesthetic spark happens when you "hear and see" the artwork through your tongue
