mxSDL:
Trippin
mxSDL: Trippin is a simple
program that does a software based alpha blend on two images I drew . These
images are Something I drew while under the Influence of LSD hehe
(SDL/SDL) The alpha blending does some neat effects heres a
sceen shot as well as the source code.
These images are the most popular
downloads on my site, to check out the LostSideDead head's stats go to http://lostsidedead.com/stats
