--EDIT-- May 14, 2013
I updated the downloadable file with a version that is compatible with Adobe Illustrator 10-Creative Suite 1-6, and Creative Cloud and hopefully beyond...
Please read the older updates for instructions and info. Also there is a Photoshop version in the comments...
--EDIT April 13, 2013---
This file is now over 6 years old. It's been downloaded a whole bunch of times and for every hundred people who tell me it works great someone will write in and say it does not work for them. there was a while when DA tweaked the way this file was presented and the thumbnail was weird and the file didn't work right. That was a while back. Now it's working right again and shows up here OK but some people are still having problems. I downloaded it myself today and it worked perfectly. Here are some handy instructions if you have never worked with Illustrator or new Illustrator Brushes before....
You can either place the file in your PLUGINS folder with the other brushes
create a new document
open BRUSH LIBRARIES
open OTHER LIBRARIES
browse for KIRBY KRACKLES FILE
open the file and only the brushes will open in a separate fly away menu box.
This file and brushes still works with the newest versions of Illustrator. I just played with it in CS6 (it was originally made for CS3 so you can see it's been a while since I made it.)
This file contains Brushes. If you open it in Illustrator as a regular file it will just look like a file. The brushes will apear in the brush menu if you have it open. The best thing to do with this is open it as a Brush Library and use on your own files as brushes, not to open it as a regular file.
I hope this helps. I hope you get a lot of joy from it as I have. 6 years-sheesh. It's been a long time. Also as part of this edit I deleted the link to my old MySpace page. believe me, it was all the rage in 2005-2006. LOL
AS OF NOW THESE BRUSHES ARE ILLUSTRATOR CS6 BRUSHES but they will work with some older versions of Illustrator if you use them from the Open Brush Library options.
THE BOOM BRUSH WORKS GREAT WITH A 5pt. STROKE ON A CIRCLE
In homage to Jack Kirby-
I just created this brush set to do some cool energy effects for my new Marvel book..
I've applied it to some art from my Iron Man Hypervelocity miniseries.
There are a bunch of brushes in the source file with various settings. I hope you get some use out of these.
I have an online tutorial blog where I teach how to draw comics using Adobe Illustrator. I draw all my work in Illustrator 10. The blog is Illcraft.com at www.illcraft.com
