We consider a set of tilings proposed recently as d-dimensional generalizat
ions of the Fibonacci chain, by Vidal and Mosseri. These tilings have a par
ticularly simple theoretical description, making them appealing candidates
for analytical solutions for electronic properties. Given their self-simila
r geometry, one could expect that the tight-binding spectra of these tiling
s might possess the characteristically singular features of well-known quas
iperiodic systems such as the Penrose or the octagonal tilings. We show her
e, by a numerical study of statistical properties of the tight-binding spec
tra that these tilings fall rather in an intermediate category between the
crystal and the quasicrystal, i.e., in a class of almost integrable models.
This is certainly a consequence of the low codimension of the tilings.
