The Beamer themes are now in the git repository:
https://version.aalto.fi/gitlab/latex/aaltobeamer. Clone or download as zip.
This page will contain the Beamer (LaTeX class for creating presentations) themes that follow the visual identity guidelines of Aalto University.
There will be two themes published when I manage to have time. Note that I no longer work for Aalto University, so this isn't necessarily on the top of my todo list.
