Whoa,
I think I remember seeing you post a couple WIP's on this. I can only imagine what you've been holding out on if this is the FIRST thing you have posted as a freebie. This is an EXCELLENT piece of work. We all love a free one now and again but you really could make at least a little money off stuff of this caliber.

p.s. on the wife thing...
Mine used to get miffed at me with the amount of time I spent "dinking around" doing stuff on my computer that didn't make money...until I managed to land a job as a programmer...which turned into a job as a CTO three years later. Now she really enjoys the stuff I put out, money making or no.
