A challenge for Jesse and Dark-beam

[PhotoComix]

And i hope a source of inspiration, already Dark-beam wrote a tutorial on how make the first example there ( the impossible triangle ) with M3D,
 a few others (i.e. the " impossible hexagonal star ") may be derived for analogy  ...but other seems impossible

Not surprising because are  beautiful example of impossible fractal figures .. but maybe not impossible for Jesse and Dark-Beam .

The "Impossible Mushroom" and the "Impossible Fern" look really cool ...
