Well im not sure what you are going after, those links don't seem to work for me
I can think of only a few suggestions in this case
1. multiple instances of particular.
2. a large + as a sprite.
3. 3d rendering (not as bad as option as you might think!... not good either)
Could you please get your examples to somewhere where we can take a look at them?
Photobucket and imageshack are two free image hosting services which will allow you to do this.
Image shack will also allow you a limited movie upload though i'll be honest, their file size restriction would bring you to tears. (as in, you have to get it under 1.53 megs, i hope you know your compression!)
