This solitaire game is visually appealing, has good sound effects and animation, and is very easily customizable. Just surf over to GrassGames to download your free program for Windows or Macs.
The free version has some limitations; however, you get all the usual solitaire variants including Klondike, Spider, and several more. The full ($19.95) version gives you 75 games in all.

If you don't like the visual presentation when you start the game, don't despair. Everything is customizable. Just move your cursor to the upper right corner of the game and choose Options. You can then go through the tabs and change just about everything about the game. The Board tab lets you change the background and even the texture of the board. The Cameras tab lets you change the view aspects which will, in turn, give you larger and/or smaller cards to suit your eyes. The Decks tab let's you change both the face and the back of the cards. You can even create your own card backs with whatever picture you have in your computer.

You are able to see many of the visual changes as you make them, so you can play with the settings until you get just the look you want. This is almost as much fun as playing the game itself.
