Have been doing some studies on Robert Silvers mosaic works and came to realize that the rectangle is replaced by the photograph or image with the most similar pixels. Wanted to know if it's possible to achieve this in Studio Artist.
Are you just asking if you can generate photo mosaic effects using Studio Artist. Yes, you can. You can use a movie brush or an image folder brush.
Some photo mosaic examples are in the gallery section of synthetik.com.
There's a mosaic tag at the top of our project blog. Clicking on it will filter the posts to show the ones tagged with mosaic.
Here's an entry into some tutorials that discuss how to generate photo mosaic effects.
