The "Crazy Effect Tutorail " is a very easy one.
To begin, I will show you the final result :
To start, create a 500px by 500px document.
Use a 72px text size and write the word you want.
Use the shortcut Ctrl-E to have only one layer and go to the menu Image--Adjustement--Invert to invert the colors.
Go to the menu Filters--Stylize--Wind and do it twice.(use Ctrl-F after you did it once because it is the shortcut)
Now, rotate the Canvas of 90CW and do the same thing.
Repeat this until your picture is like this.
Use Ctrl-U to adjust the color and here it is!
