So after asking all friends / work colleagues / enemies etc.
I turn to the experts here:
Who knows a cheap program in which you can create simple, simple animations, and these as a clip?
can export.
Something like Adobe Flash, only that is omitted because you need a high school diploma - degree in animation and film history - to be able to use it
and is too expensive.
I am grateful for about every hint in any direction, as the ideas slowly pass me by,
And I have no plan how to go about it
Thanks for your participation!
