Hi,
I tried to run
PixelToaster on
Visual C++ 2005 Express and to test it I ported a nice
effect from a java applet to C++. To make it a bit smoother I added a little gradient to the fx.
However, don't applaud me for the original fx because it is not mine (unfortunately
)...
Use your mouse to change the effect.
Here's the code
/******************************************************
/*** Hypnosis FX
/***
/*** original java version by Mario Klingemann
/*** converted to pixeltoaser and added a gradient fx
