As far as Youtube goes.. I have only one video and I'm not really in it (in person anyway). It was a video I made a long.. long time ago when I was making a (Q1) E3M7 map for Q3. I got sick of loading up Q1 over and over and over again, so I made a demo of myself running through the map.

http://www.youtube.com/watch?v=hzoFs5t33SY is where you can watch it if you really want to. I used every weapon (minus the axe), and revealed all the secrets (missed one which I had to backtrack to at the end). Other than that.. it's nothing special.
