and let it run. 100,000 iterations took around 36 hours on my older 24" iMac (at 8^1 using a modified goto.pl which only makes a difference early by refreshing every 10 seconds when I really should have been paying more attention). That alien spaceship turns up at least seven times, two of which are still running beyond 100,000 along with partial rakes from two others. But that is only the sideshow. Relatively late it provides a strongly visual example of period doubling. The rest just has to be seen. There aren't words for most of it.
