My business partner and I worked on that for a few months last year while we were slacking off and enjoying business a little too much... we haven't done much to market it in a long time, but hope to get around to it one of these days (years)...
Anyways, glad you enjoyed it... we have yet to come across someone who hasn't enjoyed it (honestly)... and it's the only product we've ever created that's NEVER had a refund (long story short, we use to sell it, but decided to give it away after a few months... for a reason I can't remember lol).
Good luck and let me know if there's ever anything I can give you a hand with.
