Spectasia

Spectasia was built to simplify searching for files on your Mac.The application showcases items in a 3D view, which proves particularly impressive on big screens.
When launched for the first time, Spectasia is in Gadget Mode, which is way too small to properly use the app.

Hover your cursor to the top right to turn it into 'Exploration Mode', simply a larger screen. This should allow you to notice the features at the bottom, like the search box or the number of items placed on the 3D board.
