Nyan cat meme with raster split

[javierglez]

I coded the Nyan Cat meme for the VIC 20 +8k (I'll post the binary in the releases thread).
It uses the stable raster split method discussed in some threads on this forum (notably the Pitfall port with has improved graphics).
The animation has 12 frames but the color attributes barely change, which allowed me to reuse the sample code without having to master the raster timings.
The unusual background colors shown are orange and light blue in the rainbow, light magenta and light orange for the cat's body, rose for the cheeks and light green for the eyes. The remaining colors which are not used are light yellow and light cyan. The VIC 20 has no grey that's the reason why the face and the limbs are white and the eyes light green.
Otherwise I think the VIC colours matches pretty much the original colors.

LOL - funny this hasn't been ported earlier yet.

The VIC 20 has no grey [...]

You might take a look at this one: VIC 20 in Black and White mode, and to quote from there:

Greyscale output is achieved by mixing green, and purple for a dark grey, light green and light purple for a light grey.

I use a stable raster routine of my own design for this.

Another method of outputting greyscale involves somewhat heavy dithering:

Nicely done! :^)

Thanks Mike, it's important to refloat these old threads, I've downloaded many things and read interesting posts from before I joined, but from time to time I come across another bunch of things.
