Has anyone come up with a nice tool for this yet? I notice that the matrix in a 2d node is not concatenating when stacking 2d transforms. So I would, roughly speaking, do something like link the 2d node's matrix to an Axis node, then do the concatenation with multiple Axis nodes and plug the result into a Card3d.
That's just off the top of my head, I haven't tested it and got it working. I know that linking matrices via live python expressions is very inefficient as each cel needs to index into the next value of the list of the same matrix, and also there have traditionally been evaluation problems on frame update, particularly at render time.
