You could have downloaded Tilery 4.2 for Mac from our application library for free. The application belongs to Theming Tools.
From the developer:
The Tilery displays tiles, each of which represents an application, document, folder, control panel, or other such item. Clicking a tile opens its item: applications are launched or brought to the front, documents are opened, folders are opened and displayed in Finder windows.
