The tricky part with using pattern paint program is there isn't much controls. It will loop the animation unless you stop it. In the picture below, I tried to manually pause it but ended up on the last colored column in the picture. <a ><img src=https://farm6.staticflickr.com/5197/14265899646_255b4ab59e_n.jpg alt="DSC_0164"></a>
Remarks: I am happy to be able to make these pictures, but it would be "cherry on top" if there was a timer display or how long the animation will take and a hotkey starter button (any dedicated key on the keyboard) that will start/end the animation. Holding down the button will allow it to loop animation until release.
If I had the programming skills, I would do something about it... Took the wrong major in college
Lastly, I would love to take this to the next level with making a series of pictures into an animation. At the moment I haven't found an efficient way to paint yet...
