Hi Scott-
That is an interesting bit of software- I had to play around with it this morning.
One downside is that it is producing a raster image with rather large dots- the test image I did was run with a 5mm dot size. You can run with a smaller dot size(to 1mm), but it is still a dot, so any line detail is going to look awfully funky.
All that being said, I think a lot of really cool stuff could be done with the software. Truly MASSIVE images.
Here is a coqui and our cat.
