Where can I get Impress manual "example" presentation?

A nice Libreoffice presentation is used for illustrations on the Getting Started guide and the Impress guide. I would like to get this file and view it properly. (some screenshots follow)

I’m also interested in the files used for Calc’s manual illustrations.
Thank you

Do you look for the presentation itself or for the underlying document template?

Either of them would be nice and both of them would be great

I think, that the design is from LibreOffice Conference in Paris 2011. Find the template at https://wiki.documentfoundation.org/File:Proposal_LibOConf2011_Template.odp. The triangle-image itself is at https://wiki.documentfoundation.org/Gallery_Motif. This template was used at FOSDEM 2012 too. I don’t know the presentations. Do you know any author? Then I would contact him directly.

I had replied earlier but for some reason it doesn’t show up. Your reply is very helpful @Regina

I’ve found it. It is in category “Conference-Templates” on https://extensions.libreoffice.org/templates/libreoffice-presentation-templates [updated URL 2016-12-04]
