will love this app as an addition to their other vector software programs. What is very important to know is Excentro, in it's demo state, has ALL the functionality of the paid version except saving it into it's native format. I can easily design my guilloche backgrounds and export it into Illustrator or Freehand for further editing.

Yes, this is worth paying for if I was a banknote or certificate designer and I need to refine my designs continuously... it's an important tool toward the tedious building of guilloche designs. But as I am a graphic designer, building a background or border in one sitting is perfect and thus Excentro is an awesome find!

My sincere kudos to Excourse for making their demo software free of crippling limitations.
