A {\it tile} is a finite subset $T$ of $\mathbb{Z}^n$. It may or may not tile $\mathbb{Z}^n$, in the sense of $\mathbb{Z}^n$ having a partition into copies of $T$. However, Chalcraft conjectured that every $T$A does tile $\mathbb{Z}^d$ for some $d$. In this talk, we will discuss some examples, and also a proof of the conjecture, recently obtained in joint work with Vytautas Gruslys and Ta Sheng Tan.
