So far no proposal was submitted for the branding of the next LibreOffice version as requested in http://opensourcedesign.net/jobs/jobs/2017-04-20-branding-for-libreoffice-60 and https://design.blog.documentfoundation.org/2017/04/21/new-branding-libreoffice-6-0/. To start the discussion I’d like to share my idea about hexagons. Unfortunately drawn very badly from the technical perspective - and maybe as well not really creative. Pretty sure you can do much better!
