The Haiku logos are trademarks, if you use it in a desktop wallpapers, this usage should follow
the usage requirements of Haiku marks:
That means using the Haiku logo should have the ® somewhere, and somewhere the follow statement should be visible:
“Haiku® and the HAIKU logo® are registered trademarks of Haiku, Inc. and are developed by the Haiku Project”.
You may resize the logo provided that
- The aspect ratio is maintained
A size greater than 150 x 50 pixels is used
- When using a logo with a transparent background, to use the correct logo
- Dark background : White wordmark
- Light background : Black wordmark
All other modifications are not allowed
Cannot pair the logo with external elements to create the appearance of another visual entity (eg " News")
Notice that using the trademarked Haiku leaf or Haiku background leaf allow more graphical modifications, though.
Regarding your work, you’re able to licence it as you want I guess. What’s you can’t do is not respecting the registered Haiku trademark by attempting to hide who own this mark, to let people think you own it,or trying to associate with something without permission from Haiku Inc., etc. Aka trying to abusing the mark.
If you follow the usage requirements above, it should be fine.
