I'm new to jQuery and really liking it. I'd like to know if there's an effect similar to IE's in which I can convert images to grayscale in the runtime?

Hi All!
I'm having an issue interacting between Matlab and .NET. I've managed to call .NET methods from Matlab code and vice versa. However, if I call a .NET method that, in turn, instantiates a Matlab object, it crashes (with a type initialization exception).
