I’m going to give a talk on DevConf and wanted to use slides with Gnome brand on it.
Searching on the web I found this that Allan Day made a few years ago. It contains a mockup in svg about how slides could look with Gnome branding.
So I went ahead and created a LibreOffice Impress template with that branding and uploaded it on GitHub with the sources for a easier use. Feel free to use it on your presentations!
PD: For Fedora branding there is this beautiful LibreOffice Impress template.
