“Mosaic” has so many possible combinations for open and closed tiles that the set can’t possibly include all of them. Instead, 12 pre-made mosaics are included along with all the files required to create your own combinations. The step-by-step instructions are in terms of Photoshop CS only, and so caution is advised for those who don’t own the software. The set is perfect for quirky photo arrangements and for highly dynamic slide shows.
