I will talk about a construction that takes a vector bundle together with a (partial) homeomorphism on the bundles base space, and produces a C*-algebra. This provides a class of examples that is both tractable, as well as potentially quite large. Under reasonable assumptions, these algebras are classifiable in the sense of the Elliott program. If time permits I will sketch some K-theory calculations, which are work in progress.
