The latest refresh of the TLGs for SharePoint 2013 contain a new version of lab configuration figures that replace:
This look and style uses a new set of standard icons that are now appearing in Microsoft Office and Exchange Server content. Feel free to use these icons in figures for your blog posts, videos, and TLGs (of course!).
For a Microsoft Visio stencil with these new icons, see New Office Visio Stencil.
For those of you (like me) who work primarily in PowerPoint, I have attached a PPT file containing the new version of the Base Configuration figure and some additional useful icons.
As always, enjoy!
