Yep,
Usage in artwork and community websites
Blender’s logo has been used in hundreds of ways. This was — and still is — considered to be an honest tribute to Blender, and the guidelines are not meant to make these uses “illegal” or “officially disapproved”. This page is only meant to clarify the Blender Foundation guidelines so that people know their minimum rights and where they can use the logo.
Modifying the Blender logo is really part of your own artistic freedom, and the Blender Foundation will never act against such tributes. Just don’t expect us to “officially approve” of it, that’s all.
Thanks,
Ton Roosendaal, Chairman of the Blender Foundation
