That is really very nice indeed

The Vortex effects ran really nicely here, the only one I can remember running almost as well as that in Freebasic was one by Rbraz. I would be really interested in seeing the source to this demo

Hopefully you'll post it to help others, but even if you don't want to post it I'd still be really interested at taking a squint at it

Come to think of it, the fire routine runs really nice too, Wouldn't mind seeing that either!
I promise not to use it myself, I am just wondering how you got those things so fast.
