We introduce a construction to "periodize" a quasiperiodic lattice of obstacles, i.e., embed it into a unit cell in a higher-dimensional space, reversing the projection method used to form quasilattices. with this construction we simulate dynamics, in quasiperiodic structures were we found a superdiffusion regimen for small obstacles and subdiffusive regime when obstacles overlap. Also we show the generic existence of channels, where particles travel without colliding, up to a critical obstacle radius, which we calculated previously for a Penrose tiling.
