New Dynamic Lights Script for XP...

[Heretic86]

New script I am working on.

Two things:
#1 - Any requested features?
#2 - Do you know of any other Dynamic Light Scripts I can take a look at?

What do you all think so far?

EDIT:  Oops!  I forgot to edit this post to put up a link to the FINISHED version of this script, complete with DEMO!

it looks awesome give it to me

I will once its stable.

My c++ skills suck bowling balls thru stir straws and the script currently is very unstable.  This is the effect that will be produced in the long run once stable:



If there are any c++ folks here, care to take a look at the source code?
