What replaces HyperCard?

[Eleonora Deak]

I used HyperCard to develop language teaching software some years ago, and
would like to bring it up to date.

I am looking to combine text, sound, pictures, and animation/video.

Can anyone suggest what software I should be looking at?  Preferably
Macintosh based or cross-platform.
