about collision routines.

[Andre Garzia]

Nice routines!!!! I am very interested in Game Development, this was 
the reason I started programming years ago (teenagers are but 
dreamers...)

I would love to be in EuroRevCon but I live in Brazil and the tickets 
are very expensive, I have not enought money to travel to malta. So I 
wanted to know if the stacks presented there will be made public so 
that at least we're able to inspect it and learn from it after.

Cheers
Andre
