Word revealing image

There are so many good image generators on the internet that I was wondering if there was one like this. I have text that I don’t want users to see immediately, but that they can see upon clicking a button. Basically, it is to raise suspense for long-awaited data. I was thinking that letters could spin, like in a slot machine, and then settle down to reveal the word or words.

Where could I make an image that would do something like this? What would be another affective way to make a suspenseful word revealer?

May not be the ideal solution but - if initial image is a thumbnail or smaller image - then perhaps you could use something like “Highslide” to produce, on clicking, a larger image which could then be an animated GIF or SWF file - that then could have the text presentation gizmos you want.
