OK, thanx Veronica. I agree that those objects are possible.
(I always did by the way).
Look at the thread and see 'simply illusions' there. Your
pictures are damn good examples how an illusuon works. When
looking at

you can't tell that this object is circular. You have to see it
from a different angle to do that. The 3D shape appeares as a
surprise (well, for some).

NOTE : This so-called impossible triangle

is also very possible but at the same time is an accepted member of the
'illusions' family. Why (still) people tend to confuse 'impossible
object' with 'illusion'.

Well that was me, though I don't call it 'confused'.
But this is a different subject ...
