1. Needs a back button. 2. It might be more illustrative if the transposed vectors pass over the matrix one by one. In the default example - you take the [2 6 1] vector and show how its dot products populate the final matrix, then do the same for the [5 7 8] vector. That's closer to the way I think about matrix multiplication.
