Hard to explain in words what i want to visual achieve Smile

i want to focus the user to a place on the GUI. i want a circular burst of color from a point, like a epicenter.

Any starting points to look at? demo code?

If you're ambitious, I'd recommend throwing ~300 particles, and then using a Delaunay Triangulator to mesh them in real time (300 for a CD or C2D; less for slower CPUs). If you vary the color by velocity and the alpha transparency by distance from origin, you can get a nice explosive (and silky smooth) splash effect.
