That's fine, as long as the final product ends up linear. What I can't stand is presentations with multiple "directions", like you can move "right", or "up" or "down". I find that to be just distracting and stressful because I'm never sure if I'm going in the "correct" direction or if I've missed something. To me, that style of presentation is a solution looking for a problem. We're going to view them in some order, just put them in that order and call it a day. If there is no order, then random order should be just fine. After all, what if you really needed more than two dimensions? You'd have to compress your ideas into a two-dimensional space anyway. Might as well make it one-dimensional and therefore less confusing.
