Holiday Greyships -- Grey No Longer!

Over the last several months, Hartmut Holzwart (with some help and suggestions from Jason Summers and others) has been building a wide variety of "greyships": extensible orthogonal spaceships with a wide variety of sizes and shapes, where the expandable central area is made up of stripes -- half ON and half OFF cells, either parallel or perpendicular to the spaceship's direction of travel.

Running these ships in MCell with the Rainbow024 palette and 17 alive states (see the Colors menu for both settings) gave some nice Yuletide colors -- figured I'd post the results here:
