Here's a go-one-further: those wonderful vector drawing controls... What
if the vector vertices could be manipulated progrmatically and the output
passed through MPEGlib to encode as an MPEG-2 stream.  One could even
write a Gambas application to do the vector editing and create a "script"
to control the vectors (Flash seem familiar here anyone???)  allowing
animation either by running the script on the vector canvas or use the
MPEGlib to play it as a streaming video.

Whether this could be done via Gambas program(s) themselves or if a
component would be needed would remain to be seen.
