Self-Similar Flags

The the popular meme shows, the flag of Norway is the “mother of flags”.

The flag of Norway contains within it the flag designs of six other countries.
The flag of Norway contains within it the flag designs of six other countries.

It doesn’t, however, contain itself (unless you don’t care about the relative widths of the white and blue parts to the whole).  In other words, it is not self-similar.

A less-popular meme points out one national flag that has this property:  the Czech Republic’s.

The Czech flag contains infinitely many smaller copies of itself.

But there are more examples.  For one thing, any bicolor flag has this property:

Flag of Monaco.
1200px-Flag_of_Indonesia.svg
Flag of Indonesia.
Flag_of_Poland.svg
Flag of Poland.
Flag_of_Ukraine.svg
Flag of Ukraine.

(The flags of Monaco and Indonesia, basically the same design, also contain copies of each other in themselves.)

Seychelles’ flag, though far more complex (five colors!), is also self-similar.

That’s it for national flags.  Looking farther afield, there are many other bicolors and a few other tricolors of the Czech type.  Single-color flags, like that of Qaddafi’s Libya, are self-similar, of course — uninteresting so.

Here’s a self-similar flag of four colors:

International Maritime Signal Flag for Z (Zulu).

And, finally, there are the many heraldic gyronny flags.  Here are two examples:

600px-Flag_of_Celles-lez-Tournai.svg
Flag of the Belgian commune of Celles-lez-Tournai.
800px-Bandeira_de_Lisboa.svg
Civil flag of Lisbon, Portugal (version without the coat of arms).

Are there other kinds of self-similar flags not covered here?
