While creating this Gallery sample we've used the technique that is described in details in the
Simple Integration part of the
Embedding an Object into the Puzzle Pieces tutorial.
Here, a Star, Hands, a Cat, etc. (except the phrase "AV Bros.") that we've used as the Objects (in terms of the mentioned above tutorial)
and which were embedded into the pieces, were taken from the Adobe Photoshop's built-in gallery of Shapes.
