 L by a path P in Z
 ²
 is unique, except in one case, up to integral
 translation. We study this exceptional case. For irrational ρ, the
 projection of P to L yields two quasicrystallographic tilings in the
 sense of Lunnon and Pleasants [5]. If ρ satisfies an equation x
 ² =
 mx + 1 with m ∈ Z, both quasicrystals are mapped to each other
 by a substitution rule. For rational ρ, we characterize the periodic
 parts of P by geometric and arithmetic properties, and exhibit
 a relationship to the hereditary algebras Hρ(K) over a field K
 introduced in a recent proof of a conjecture of Ro˘ıter.
