A good general introduction to tilings is Open Questions on in Tilings, though I now believe every conjecture in the paper is incorrect! Some general interest papers on tilings are A small set of aperiodic tiles and Aperiodic hierarchical tilings. The papers Dodecafoam and substitution tilings and Compass and straightedge in the Poincare disk are meant for a wider mathematical audience.
