Awesome modded EVO frame!

So i picked up one of the sweet old Noleen DH forks a while back, and I emailed k2 asking for some information about it. Well, I"ll post something else about this fork (because its a sweet fork), but the tech I talked to had one, and we got to talking for a while. He eventually showed me this sweet evo he'd been working on! It supposed to mirror the linkage on a motocross bike, moving the shock toward the pivot during compression(more progressive). I guess this is his first prototype, and he's gonna make a steel one later! Anyway, I knew you guys would think this is awesome- [smiley=nod.gif]
Heres the link in case it doesnt work:http://idriders.com/proflex/files/mikesbike1.jpg

Is there anyway I could get a copy of any blueprints? It looks like it would be a sweet project to experement with.

it looks hardcore but i don't understand what the linkage does. the shock and pivot position are about the same as normal. Any engineers out there who can explain?

Not an engineer, but a scienist (who spells poorly). In space the shock moves in relation to the pivot point. A pivot is a fixed point on the frame, the whole braket moves to allow spring progression... and, if I remember my physic right, the assembly would "self-dampen" (there is probably a scientific word for the phenom)
Look closely at the bottom pivot. That is the easiest place to see the difference. the schock moves along a curve, not merely pivots.
Over simplified, by a guy who is a chemist, not an engineer.

I suppose the linkage would change the rate of the linkage towards a falling rate. But doesn't it look like the shock mount would move away from the pivot upon compression rather than towards it?
