Composite Nodes Question

I have been noticing a few very well done examples of this lately. My question is, can effect be done without nodes, and if so, how?

well… you can do a lot of things with the Composite nodes editor… if you are not very specific with your question and the kind of effect you’d like to attempts, it’s really hard to give you pointers, aparts from pointing you to the excellent wiki documentation…
Basically, the editor is very versatile, thanks to the coders, and once more time proves that Blender can be, most of the time, an excellent stand-alone program with all the useful tools in the very same pipeline.

i am ofcourse refering to the 3d artwork that looks basically drawn.
