I'm not much of an illustrator fan, but I'll admit that these patterns looks pretty darn cool! I actually HAVE been wanting to get back into illustrator (for career purposes) and this plug-in may be the very thing to get me to jump back into the pool.
In terms of vector art, I much prefer using flash, but even that program has its limitations. I guess I'll have to man up (or girl up. lol) sometime.
