It can be really effective if you add a slider to let the user control the amount of wipe. Also, being able to choose different wipes is useful. http://en.wikipedia.org/wiki/Wipe_(transition) This is called a “matrix wipe”.

I do this by making the image greyscale and using the metric to overlay colour, using a colormap like jet. I use my SC function (on the FEX) to do this for me, using the 'prob' or 'prob_jet' colormaps.
