Lol,I love this guy,lol,Thanks for being you TechnoRobbo.      Just when I think you can't possibly top your other cool plugins you pop out another one.  This one looks like I am going to have some real fun with my family pics,heh,heh,heh.  If you don't see me for awhile it's because they hung me,lol.

Damn.  For code that short, this plugin shouldn't be this much fun.   I love the video!

This will be cool for adding some Salvador Dali styled mutilations to images. Nice one

Skull and EER

Thank you for the kind words.

 

and EER ,

 

It's not the size of the code but how you use it.

DD,

 

That is exactly, I mean exactly  what I was thinking. I wanted to melt alarm clocks. Before I even had one ounce of math on my spreadsheet I had the name "TR's Dali Plugin". I then thought that might be too obscure, I learned my lesson with Bokeh, so I made the name something you could visualize.

couldn't resist
