I helped optimize the first sw dvd player (SoftDVD), which managed to 
keep up without any frame dropping on a PentiumMMX 300.

I did a similar (i.e. very small indeed) amount of work on the original 
Quake, enough to be mentioned in the manual.

You might find some traces of the work I did for Intel, optimizing their 
h264 decoder: This was mostly a case of showing them that 'Yes, it might 
indeed be possible to double the speed of your current code."

You might be able to locate my 3rd place code for Conway's Game of Life, 
or the Word Count which Mike Abrash have written about.

The code I won two different competitions for (a Pentomino solver) is 
quite nice, even the plain C version was significantly faster than the 
second-best asm entry.

(It won twice because somebody entered the C version in a French 
competition! :-) )

I also did quite a bit of the work on DFC (Decorrelated Fast Cipher), 
one of the also-ran candidates in the AES competition.

There's been a bunch of other things over all the years since 1982, but 
you'll probably never find them. :-)
