Most definitely, as a found splash of paint with a happy lapine likeness, the Five-Legged Space Rabbit of Whitley Bay hops under the Creative Commons Attribution Licence.
That means anyone is free to share it or adapt it for any use whatsoever - even commercially.
No attribution to me, by name or in any other way, of the original concept, is necessary. Check the licence out for all the details.
Because the Five-Legged Space Rabbit is a soft anarchist, a trickster and transformer, and really wouldn't have it any other way. Probably.
I'm umm-ing and er-ing over the degree of creative commons licence I wish to apply to my other work - photos and stories, including the characters Wind Boy and Sloth Man - and will make the whole thing clear when my cogitations have stopped.
