Hi - I'm a co-author of the above mentioned Quaternion package. I agree the numpy_quaternion version would be better, but if there is no expectation that it will move forward I can offer to improve our Quaternion. A few months ago I played around with making it accept arbitrary array inputs (with similar shape of course) to essentially vectorize the transformations. We never got around to putting this in a release because of a perceived lack of interest / priorities... If this would be useful then let me know.
