the calculus might not work as expected....
hmm....

Indeed, it's wrong - I've submitted a corrected version.

I thought it might be multiplying instead of adding, couldnt't find clear examples or description in the universal-wiki though. :(
It does work for simple rotations of 90degrees. :)
In the only succesfull attempt at a double quaternion, I rotated around the x/y diagonal 90 degrees.
(That would be the vector 1x,1y,0z ?)
I ended up with Q = 0.707 0.0 0.707 0.383 though.(x,z pos or negative depending on up/down, left/right orientation)

Why can I not multiply a 180degree turn with another?
