Reveal a picture piece by piece
<p>I am trying to reveal a picture piece by piece. I found this thread here <a href="http://stackoverflow.com/questions/5957789/need-ideas-to-only-display-some-pixels-and-gray-out-the-remaining-pixels">need ideas to only display some pixels and gray out the remaining pixels</a>, with an excellent answer from mVChr. This is almost what I'm looking for, but I would like to make the revealing pieces larger, so it takes less time to completely see the image.
What do I have to adapt in the code?
Anybody able to help me?
Thanks a lot for the effort</p>
