A blob is a decoration on a Temperley-Lieb diagram. A ToR is a device for organising functorial machinery in towers of algebras. A Hecke algebra is a certain tower of algebras with interesting finite-dimensional quotients. We use blobs and ToRs to determine decomposition matrices for certain such quotients—an approach inspired by statistical mechanics.
