In the versions exhibited here, the sitter's benevolent expression has been slightly intensified in order to achieve an equivocal effect. His enquiring gaze is directed at eye level, assumably towards the feet: where are they headed to and who sets them in motion? Are those poses determined by muscle tension or by the floor's properties?

This raises vast and difficult questions on the topic of free will. Perhaps the foot poses depicted here are mere whirlpools forming and drifting across the surface of the endlessly complex stream of reality.
