You can think of the random possibilities as exploring one path through a huge tree of possibilities. You can then pick 9 paths for the next step and have the user choose the one they prefer and keep repeating until the user feels that they're done. We used to use this sort of approach to produce random shapes for animation and display on large screens in clubs in the mid-90s. You can also animate by tweening one or more parameters at particular branching points or between branches. If you pick the right places on these ships that could produce some interesting movement in the craft as well.
