Not the OP, but I learned how to solve them not long after they came out. I solved one on my own, but it was more about learning a series of logical moves and applying them, along with some trial and error and some luck. I then learned a method of solving the cube from a book which I can still do to this day. But there's no visualization involved. I just look at the cube, notice that these particular faces are in this configuration, then apply the appropriate sequence of moves to get to the next step. Rinse and repeat.
