I'm over at Ian's place at the moment. West Chester, PA, suburbia at its best :)
Everytime I come over he makes me do something weird. This time he made me write a bumpmapping algorithm for him. It's mostly used in 3D computer games, since it makes really nice textures. Why did he need it? I'm sure he'll tell you sometime soon in his blog. I'll move the bumpmapping algorithm to kdefx KImageEffect after 3.2. Also if you know any graphics algorithm that you would like to use with QImage's let me know. Either send me the name of the algorithm and the app which implements it, or preferably math behind it.
