One of the projects we maintain is CommuniKate. It’s an open-licensed page set for use in AAC devices. Notably, it was the first such page set and thus gets used in lots of small (and large – see e.g. Optikey) open source AAC software systems.
We got a lovely message last week to say that it had been used in a new webapp called Life Companion, and, as a bonus, has been translated into French.
