  I mainly care about breaking assumptions in ways that inspire other people to explore new areas, as has happened successfully twice now.
  
  I don't hope this entry into the fight inspires people to make demos without sound.

  
  Ok, you keep breaking the assumption that the code should be compatible to inspire people to do incompatible things, or keep breaking the assumption that we should take these challenges with sportsmanship to inspire people to kick like children in defeat, while I just break records :)

  Hannibal still in the lead. :)

  
  Hehe, good try but I'm sorry, it's not Blueberry who decides who is in the lead, but the number of columns in the rotozoom. :)

  Instead of meeting that challenge and beating previous records, Rhino decided to tackle a different, easier problem.

  
  XD It is funny, I hope you're joking and not taking your defeats so badly bc you are talking about yourself here: Instead of meeting the original copperchunky challenge and beating previous records, you decided to tackle a different, easier problem (as the speed and number of records after yours have shown) making your code incompatible :)
  
  Anyway, In demoscene you don't win records with words, if you can do it with more columns at full dma music, just show it in a demo :D

  I wonder why it's repeating the same movement over and over...
  

  
  Well, I think there are several reasons why I did it this way:
  
  1. This is done in a few days without worrying about small details.
  
  2. At such a low resolution, constant rotation on a fixed axis make the movement smoother than if you try to make complex movements involving translations, etc...
  
  3. It is a classic trick to speed up a little more the rotozoom by precalculating the X and Y offsets of each frame (64 X offsets + 68 Y offsets). It's a brief pre-calculation of about 100kb of data that happens at the beginning, during the fraction of a second with the colour bars. It is true that I could have made it 4 times bigger to be less repetitive, as there is enough free memory for it, but the important thing is that it allows me to add about one of the 11 rows by which this rotozoom outperforms yours. (The other 10 extra rows are due to an old Amiga hardware trick that even Photon knows about. Feel free to ask if you can't find it after examining the code :)

• That question is best answered with another question: What is the widest 4x4 RGB rotozoom?

• @Hannibal I haven't looked at your code to see the technique you use, but if it's based on a way to avoid the ‘anti-aliasing’ of HAM, then the width challenge doesn't make sense anymore because with this technique you could make it any width, including the maximum overscan width? Or is there some limitation why you couldn't make it wider than 80 columns?

• This is what happens when you remove the “copperchunky” restriction on this challenge xD
