i used to convert all my low-res anims to interlace and then run them through clarissa. It made a a big difference to the smoothness of the animation. I understand Clarissa splits each frame in two and shows every even scanline in one and follows immediately with showing every odd scanline of the same frame. I don't know what the bandwidth implications are but the results were much much smoother. I'm not sure that Clarissa can run on a 1 MB A500 though.
