Here are a few more greyships and related patterns constructed recently by Hartmut Holzwart:

The following two patterns are "failed spacefillers" — they expand in the same way as a standard spacefiller for a while, until an internal instability in the boundary between the two types of stripes catches up with an expanding edge.

These last two patterns, along with many of the greyships from previous postings, can also be seen here in MCell holiday colors.
