This work is really magical. Great tune!

I tried running the PRG on VICE, but it fails with "?SYNTAX ERROR IN 2059".
Is the file corrupted?

"MULTIPLEXIUS" so maybe each sprite gets 8/9 time, and the flicker is not noticeable? I don't know, I was an Atari kid.

It seems obvious that some kind of wire or string is used by the magician to float those numbers as they are always only floating horizontically but not vertically. I bet there are at least five people in the ceiling puppeteering all those numbers around. As we just saw a video of the trick perhaps further editing - removal of said strings - is involved.

Each number is built from parts and there is 8 types of that. Am I right? That's the reason of 7 shape.

Edit:
Oh, you shared code. I will check that soon.

Did not see where the code was shared, but anyway, lovely demo, and above the nice trick, It's just juicy from a art perspective. I love it !

Did you use interlace. That would let you move a sprite from the upper half of the screen to the lower half by using a hardware interrupt. Many games, like Commando, used this technique. /Thomas

That is not what interlace is about, and yes "sprite multiplexing" can allow you to reuse sprites again vertically , which is why the demo puts them side by side horizontally to show that it is not as simple as that old trick.

Sprites were multiplexed across vertical raster lines (over 8 sprites, sometimes up to 120 sprites). Until the Group Crest released Krestage 3 in May 2007 there was the common perception that no more than 8 sprites could appear at one raster line, but assigning new Y coordinates made it reappear further down the screen.

My guess is that one number is made out of characters and the characters' pixels are animated (changed in memory)

Can't be in the border then.

Open top border creates a junk char, you can place the sprites behind it. You could smooth out chunky multi-color sprites this way, as a type of anti-aliasing, so I think the top part is sprites placed as a bitmap, the reason they stay closer together.

If each number is a sprite, then 6 and 9 share the same sprite code (just flipped). I'm 64% sure I am correct.

C64 allows you to mix and match any sprite data as it's just a pointer to a memory location divisible of 64, but it does not allow you to tell it to draw the sprite flipped or mirrored.

Wide the side effect that the whole sprite engine missed the start of the next line, the reason they use a windowed font.

Here is a very good analysis of the demo:

And indeed the demo is very much magic. There is not a single trick being used throughout the demo, but just like a great magician makes you believe something through smoke and mirrors. Extremely well executed Linus, huge props.

Except it hand waves the top border effect, which has something to do with ghost byte and sprite crunch.

Sprite re-using is a decade old trick on C64. Even large/multicolor images are made with the help of multiplexed sprites (1. combining with normal char/gfx screen makes possible to break the 4-color-in-a-character barrier 2. sprites can be displayed on the border area).

Awesome demo. Wonderful soundtrack -- thank you for posting an MP3 version too!

Wow, supernajs!
Vilket jobb och nogrannhet att fixa var enda liten pixel av utdragna spritar till att bli täckta med pixlar på varje enskild position för att se ut som om de är fyra gånger så stora, dessutom så smörmjuka animationer, verkligen imponerande!

I added a short code for loading "Nine" directly from here using a Meatloaf device.

LOAD"ML:NINE",8

I love your art! :)
Thank you LFT!

Hello Linus - In primary school, in BASIC, the most advanced thing I could write was to get my C64 to display a sprite of my design and move it around the screen. At that time, I was aware the C64 could manage 8 of them. I haven't played with the C64 much since.

It was with this background that I watched your 'Nine' video its accompanying explainer. Super fun to see you explain the additional tricks to achieve impossible effects.

Also - it's just a fun demo artistically, with the magician, the timing, and its soundtrack - I've shared with my father & a few of my childhood friends with a shared C64 experience. Thanks for building, sharing and explaining your work.

Hey, Phil gave me some tobacco Thursday, and it had some pot in it, I got a bit stoned and watched NINE for the first time, and it took on a pot induced spiritual meaning, , ha ha - Here are our songs, and a couple of CHIPTUNES on my mini webpage

I just put the NINE MP3 and VIDEO on my page !!, , And Oh yeah, the SID drum, , the best sounding C64 drum i've ever heard in 41 years, , , ha

Hmmmm, just thinking of how LFT timed it, the numbers leaving\entering the hat is spot on with the beat of the tune, , and the general animation, , , He must of used the note data as some kind of reference ? !!

Haha, , the swirling spirits don't adhere to the laws of motion, they do the opposite and speed up as the circle widens, , ,
