comment Subtract gravity from 3D object in different orientations
@Steven: Yes, there is that important caveat. Well, if you know how to do matrix multiplication, then you can derive the matrix yourself by multiplying the three simpler rotation matrices in the proper order.

comment Subtract gravity from 3D object in different orientations
@Steven: Huh, interesting. I didn't do any testing myself, I just found this matrix and did the relevant multiplication...so I suppose it's possible they had a typo or something.

comment Number of ways of spelling Abracadabra in this grid
I think your problem is that you're treating picking the "A" as one of two choices, when there's really nothing you can do about it. Two routes to a B and two from each B to an R gives $2*2 = 4$ ways.
