You could try 3D rendering. After all, the ubiquitous LightWave3D started out on the Amiga.
Now, there are umpteen 3D packages for the Amiga which enable anyone with an artistic bent to create veritable masterpieces.
I'm into LightWave myself and I use a relatively modest A1200 to create all my website stuff, which includes some 3D animations.
Check out my site at:
