Well, I'll explain. Rob sent along this picture of his lugged '92 Paramount and asked if I could build a modern lugged 29'er. Not an easy task considering the extreme angles that suspension corrected 29'ers present. On the upside, Rob's a pretty big guy and that helps make some of the angles less problematic.
I decided to go with a standard size seat tube, 28.6mm, externally butted at the top, and then a 31.8mm top tube and 35mm down tube. A set of double bend chain stays and Paragon chain stay mount disk dropouts finishes things off. 
I spent a fair amount of time figuring out where to locate the bends and bumps when I built my 29'er last year, so I knew pretty well where to make my cutoffs and bumps for tire and chain ring clearance. I did have to do some work on the chain stay sockets of the bottom bracket shell. It's a road shell, so the sockets are not angled as much as you need. After some subtle persuasion, they came around.
I used some 4130 tubing to make the Bi-Lam lugs. First I mitered the end to match up with my geometry, then I drew my design on the tube and cut it out roughly with a hacksaw. Once I had a manageable sized stub, I tacked it onto the head tube where I could do the final shaping. Below is the head tube with the top and down tube "lugs" attached. I made the down tube lug a little extra long on the bottom to act as a gusset and the forked tangs should distribute the stress outward.
The tube set, lugs and chain stays all ready to be brazed.
A better shot of the bi-lam head and seat lugs.
Once it's finished the Inspector has to have a look! The cable guides are brazed onto the head lugs, reminiscent of Rob's Paramount.

Paragon dropouts. I'm really liking these!

"I guess this one's OK"...

Jason's frame uses True Temper's S3 tubeset. The seat tube is round, while the top tube and down tube are pretty heavily shaped. They're also quite thin, and this helps bring Jason's frame in at under 3 1/4 lbs. 
And a shot of the head lugs as I carved them out of a piece of 4130 chromoly. 
Frame is all fluxed up and ready to be tacked.
Head tube, brazed and soaked to remove the flux.
The inspector stopped down for a quick look, but she's more interested in sneaking outside now that the weather's nice. 
Finished bottom bracket fillets.
Here's a shot of those nice Long Shen head lugs, very clean and nice.
The seat cluster area, lots of stuff going on here. You can see the top tube cable routing, (which I don't normally do), a beefy canti brake bridge, and the hidden rack mounts on the inside of the seat stays. What you can't see here is the internal routing for the front derailleur cable. Since Carl was only going to run a front changer infrequently, I routed it under the top tube internally. This way, when it's not being used, you don't have open cable guides except the one on the back of the seat tube. 
Oh yeah, the vintage Campy dropouts. If you look close you can see the pitting from some years of rusting away at the Paramount and later Waterford shop. Saved a pile of these from the dumpster during my Waterford days. A little vinegar and salt soak and they're ready for action!
I talked to so many people over the 3 days of NAHBS, and got such great feedback on my frames. Folks commented on how clean, simple and classic they looked, and that's exactly what I'm going for every time I start a frame. I'm honored that the judges felt my frame was "Best in Show", but I'm sure there were at least a dozen other frames that could easily have won in it's place.
