Dear Dalyoung, dear Mikael

Thank you both for your explanations: indeed this =C2=AB whatever =C2=BB =
command in MetaPost is magic and very useful (I am not sure whether it =
is a command only in MetaFun, or it exists also in the original =
MetaPost).

Regarding the way Aditya uses \startuseMPgraphic, it is also very =
instructive.=20
Dalyoung, can you also share the animation example for the foldings ? I =
am sure we are a few on the list to learn something=E2=80=A6

Best regards: Otared
