A herculean effort and one you should be immensly proud of!
Truly, this is
the BEST 3DGS tutorial to date...Period....better than the manual (duh

) and infinitly better than Alains.
As a conclusion to your project, what, in your opinion, is left to do? You stated that there was alot you didn't get to do, but I would like to know what direction you could see for chapter 12, 13, 14, etc. Give us a list so that someone can take up the torch you have single handedly borne these last few months.
Also, do us a favor....Don't submit to the contest....otherwise, there really is no point in anyone else submitting!!!!

(<---joke....you DESERVE the $450 and then some)
