holy ™ is an agency of all sorts of services, from branding all the way to the user interface design.
Rebranding for fun might be a prohibited thing for some, but what the hell? If people can't practice, develop their skills, then what's the point of even trying? Justin Marimon, a designer from Chicago, made everyone a favor and made his own rebranding for National Geographic.
We need more projects like this. People need to keep making experiments, rebranding well-known companies for the sake of creativity. For more of this rebranding you may visit Justin's portfolio at Behance... there you'll find much more examples of use. I hope you enjoy these, and please, leave your negativity outside the community. Let ideas and inspiration flow, people. Cheers! ;)
