Adobe Photoshop - Okay, it's expensive and probably a little too powerful for making your own Shadowrama images.
Paint Shop Pro - This is shareware and allows you make wonderful Shadowrama images. It's a trial version, so I think it's only good for 30-days, so don't even try to set the date on your computer to the year 2010 before installing it and then move it back to the current date to give you well over 30 days, because THEY will know!

Here are a variety of Shadowrama images:
