Four-Dimensional Soyjak

A Four-Dimensional Soyjak (also known as a Tessejak) is a hypothetical soyjak which spatial properties are 4 dimensional in nature. It is likely that if this Soyjak did exist, it would be impossible for it to be fully perceivable to the naked eye with only one of the infinite 3rd dimensional "layers" that that it's made of being visible (though it is likely that one can picture this object in the mind).
