Well this is a start to my entry. Right now its obviously not very flexible but I'm planning on expanding these calculations to accept parameters such as grain density, knot freqency, knot size, texture size, wood scale, and color. I'm not using any specific algorithm, just messing around and seeing what I can come up with.

Really nice looking wood texture :)
-
What Shocky says!
-
That's a good start man. I bet you could make some really detailed stuff with a bit of tweaking. :)
-
definaley wood grain lotsa variety coming in for this compo :D
-
Welldone Deleter :)
-
Nice texture, I like it.
-
Little number tweaks:

(still have to make the knot position "random")
-
Thats cool, it looks almost Sketched!
-
I really like that, hope you keep working on it!
It's not so far away from what the pros do (http://www.filterforge.com/filters/284.html)...

I really like the notion of using math to create forms that mimic organic structures. Very nice.
