BOOM. DONE.

This is my first review because this app was *so* good it warrnted me actually spending the time to write this. So easy, so fast. I had many, many gigs of images and it happily mosaiced them in seconds. It can write enormous images -- up to 15,000 pixels on a side. *Exactly* what I needed. Thanks, Mosaik.
