• 256b MS-Dos Puls by Řrřola [web]
• Thinking it out in C and sketching it out in asm took about a week, byte crunching took another one... that's like forty hours of full focus and eighty of playing.

• What is it: implicit surfaces raymarching using binary search. The shapes get "blown up" according to step size, which fakes the ambient occlusion feel (also necessary for the bisection to work). Color is the number of missed probes minus log(last step size), which had the most bearable artifacts.
  
  Windows version: I think it would fit in 1k easily – I was just playing with the effect before switching to asm. I'll update it and release the C source after Function.
  
  whoa, thanks for the cdc's... O_o

• Thanks for all the nice words, and for putting it on scene.org and youtube - my free hosting would shut my site down with all the traffic. ;)
  
  The Windows version was a proof-of-concept and uses 4x4 progressive raymarching, that's why it's faster. I'll expand it with the intro color and parameters in a week or so.

• 256b MS-Dos Symetrie by Řrřola [web]
• I've added a Windows screensaver version to the zip. It's just a test version ;). Any feedback will be appreciated.

• demotool Windows Crinkler by Loonies [web] & TBC
• That was new to me. You really should write an article about Crinkler's headers - I doubt anyone has tested the whims of various loaders as thoroughly as you. It would make writing custom compressors a lot easier.
  
  So, I guess the days of the lz32.dll import are over now? :)

• See http://www.harmonysecurity.com/blog/2009/06/retrieving-kernel32s-base-address.html - it's only 2 bytes larger.
  
  Also, all programs are called from kernel32:BaseThreadInitThunk, so you can use 11 bytes to get the base:
  
  EntryPoint: ; can be 1 or SectionAlign+1
  pop edx ; 'Z'
  push edx
  FindMZ:
  dec edx
  cwd ; AX must be set <8000h before
  cmp word[edx],'MZ'
  jne FindMZ

• 256b Windows ROXOR-2A by zerofun
• It works fine now. I wonder whether there's a tutorial about which PE header fields are safe to change/overlap so that it works under any Windows (2k+). I've seen TinyPE and made a few attempts (no setup file: kernel32 lookup from stack return address + LoadLibrary + import by hash), but I'd like a reliable method... maybe the Crinkler guys know something?
