a lot of reasons: MPEG1-codecs (or at least, the decoders) are included 
with every major OS, so everybody can see it, MPEG4 needs a faster 
computer, which not everyone has, and there appear to be a lot of 
sub-standards for MPEG4, so even if you have *an* MPEG4-decoder, you 
might not be able to see it.

It's more or less the same with MP3.  There are better alternatives than 
MP3, OGG Vorbis for instance, but everybody can play MP3 without hassle, 
which is not the case for OGG Vorbis, so MP3's what you should use if 
you want people to hear your music :(

To comment on the animation: looks good (except for the MPEG-artifacts 
of course :)) !  Is it just going to be spheres, or are you planning on 
making it a real (customizable) rollercoaster-object?  That'd be cool :)
