Spun from gossamer thin bimetallic threads this flag would breath like Egyptian cotton... if there were any atmosphere, but on the lonely Lunar landscape though direct sunlight alone will cause portions of this fabric to straighten against the weak gravity only to find that portion then shaded by another
portion of the cloth becoming heated in the solar breeze.
Weave patterns will need to be experimented with to obtain the most realistic wave forms

Nitinol doesn't behave like that. You're thinking of bimetallic strip. |
|
| |
When warmed above a critical temperature, nitinol reverts to the shape it was before it was distorted at lower temperature. |
|
| |
Once the reversion has occurred, it's necessary to cool it below the critical temperature and then mechanically reshape it. |
|
| |
Minor technical correction, interesting, and perhaps
workable. |

really? If the nitinol mesh were made to be flat when illuminated then when in shadow gravity would pull the cloth downwards. Sunlight would not fall evenly on its wrinkled surface so only portions would try to become flat again while shading other portions, but okay I believe you. |

Interesting, but I suspect the flag would settle into some sort
of equilibrium, changing only slightly as the sun moved. But,
in theory, it might just work... |
