| The scroller bugs on real hardware. It shows garbage in the charset where one expects spaces. The garbage is gone when I fill the RAM with $00 before loading and running the intro. |

| Kinda sad to see top half empty but otherwise cool one. |

@Compyx
there is the charset for the scroller :D and the scrolltext that's the eason why it is so short scroller ;) |

Sweet. Nice colours in the logo too.
The minorest of missed opportunities though; the animation is *almost* in time with the music; there's a half beat every 12 frames, and a new animation frame every 10-14. Do you have enough RAM left to triple buffer?
I do like the overall composition; the blank upper half of the frame works well for me.
Oh and speaking of the music, it's pretty ace. Happy to leave that one running while I try and get some work done this afternoon :) |

| What happened to the top half of the screen? |

thx all...
positions of vertices are precalced (boooh ;)) but fractal lines not... they are called and rendered each frame...
but Bitbreaker et al will beat that some day :D. |

| I probably lack the mathematical background to fully appreciate what's going on there but I like it nonetheless. Looks like it repeats the same sequence of wave states though, so maybe it could be sped up quite a bit with pre-calculated data? |

| Yes, relies on not initialised memory for space character. |

| Nice effect, but scroller seems to rely on zero initialised memory (?) ... at least it shows strange chars instead of space with AR/RR here. |

| Looks very nice, but uses mem from $0801-$5bfe, which is a pity because $0400-$1f00 looks totally unaccessed after the prg has launched.. |

| yeah koronis and fractalus are exactly what it reminds me of |

If you might wonder why it’s so slow... well... the fractal line nature is recursively called and based on Carpenter released around 1980s at SIGGraph and based on midpoint displacement while edge displacement is based on some V and C flag trickery.
Rescue on Fractalus, Eidolon and Koronis Rift work similar but Charly’s Implementation there works different but based on Carpenter’s work, too. RoF can “just” generate 16 types of lines (characteristics) while the algorithm I used can generated 256x256 types. Research is based on Popmilo and was first used by me on Atari 800 in Arsantica 2 and later in Arsantica 3 etc.
The C64 implementation here is adapted for the slow CPU. ;) |

@No-XS: Lead notes are a bit... "ordinary" ,D

| There is a reason why there is nothing on top half ;) |

effect is cool, points to improve:
- silent beginning and music starting without any clear reason while visuals are already shown and runnning for a few seconds
- some action in upper half of screen? |
