The very last scene of the OP sequence requires a very small, almost indiscernible animation of Cyllia that's displayed on Kana's netbook -- since the animation is small and obstructed by light, no major detail or shading is required. Hence I was able to create the above animation of Cyllia relatively quickly, thanks in huge part to Inkscape's efficiency. Only the first frame was "drawn", the rest were created just by duplicating and repositioning each individual body part.
The in-game animation is not nearly as detailed or colourful (or includes that TV-Out animation towards the end), but is made fancier here just for show. ^__^
The animated GIF itself was constructed in GIMP.
