FYI - buzz.Professional
From Segmentis

buzz Professional is comprised of thirteen filters.  These filters, when combined, can create a myriad of special FX.  Each one can be added on top of the next one, and rearranged into a different order by dragging and dropping then in the pop-up dialog box, thereby creating many unique FX.  I've used some of the preset settings for the examples below.  Scroll to the bottom for a look at the two dialog boxes that buzz Professional uses.  As you add filters, your main dialog box with the preview grows to accommodate new filter controls.  Settings can be saved for later use, and they are saved as individual files that can be shared with others using buzz Professional. 

In this box, you add filter FX from the left, and stack them on the right.  If you want to change the order of FX (the order can make for a huge difference in the final image) just drag and drop the one you want to move.  It's that simple.  If you change your mind, just move it back, or remove it entirely.  All of the FX shows up in the preview, and is not applied until you hit OK.
