• intro Windows fracture, part2: infinite mandelbrot scroller by Quite
• I am not sure what kind of effect is this (fractal as someone said?) but it fit so perfectly with the ambient music and my current mood.

• demo Windows Quantum by Outracks [web] & Nazareth [web]
• Good final, a lot of improvements, it doesn't end so abruptly as the party version, even though the end is still poor.

  then they make an unroll code working for one scanline where instead of add cx,si and add dx,bp for example, they have most of the times on inc ch or one inc dh or nothing, mixed, because during the interpolation one of them if not two might change by one or at some pixels there could be no change

  
  
  Also,. with this logic more stuff can be removed, if from one pixel to the next when adding the gradient doesn't change the high value (you are still at the same U,V on the bitmap) then you don't need to reread the pixel since it's the same. I mean, you can remove more code than only the ddx, ddy adds in many places (and that always depends if the rotozoomer is closer to the viewer, less incs and rereads of pixels). Anyways :)

• Thanks for the code, it's tight and interesting :)
  
  A faster and different code is how, I think (I am not sure but I guess) some CPC coders are doing the rotozoomer, which although makes their rotozoomers ugly and less accurate when zooming close. They don't add the dx and dy each time but they have many different unrolled codes for each gradient. Since in one frame you have the same ddx and ddy for each scanline you render when moving on X, then they make an unroll code working for one scanline where instead of add cx,si and add dx,bp for example, they have most of the times on inc ch or one inc dh or nothing, mixed, because during the interpolation one of them if not two might change by one or at some pixels there could be no change (only if the precalculated unrolled codes are for the rotozoomer frames closer, more zoomed in to the viewer). Although it needs a lot of precalcs (if in a rotozoomer looping animation there are 200 different gradient/zoom combinations you need 200 unrolled code precalcs for one scanline of pixels) and is kinda ugly when it zooms in. It's a bit strange to explain but I think this is how they do it a bit faster than my current attempts on the CPC.

• 4k procedural graphics Windows Sollbruchstelle by Laeila
• Nice for a first.
  Unexpected winner (I really wonder why brix came even 3rd?).
  Motivational thumb up.

• demo MS-Dos abort retry fail by The Dennis Courtney 5
• Thanks for the video. I start to like it even more. It's really funny, has great references (dr sbaitso), hamster anim in msdos and greatly synced with sound and style. Also, thanks for the greetings, I rarely get some :)

• I liked it a bit better now I watch it again (I have to admit that I pressed escape in the middle the first time). Certainly not what I expected by the comments and graphics but it's rare to see such kind of demos and I want more.
