Rubik's Cube

Designed for Yahoo! Widget Engine, this is a desktop game that mimics Rubik's Cube, where it's necessary to match all squares by color using various algorithms. You can use the mouse cursor to move the cube tiles as well as click a button to scramble them and restart the game.

Scramble cube tiles and reset the game

Provided that you already have Yahoo! Widget Engine installed, it's easy to set up this application. By default, the cube has matched colors, so you can get started by scrambling the tiles.
When Rubik's Cube is the active program, it shows three mirrors on the left and right side of the cube, as well as on the bottom, so you can get a view of all sides and carefully plan your next moves.
You can click one of the displayed arrow buttons to move the row in the corresponding direction, reset the game or scramble the tiles again, as well as click on three smaller images representing the cube, in order to change the perspective and concentrate on another cube side.

Pristine or worn-looking cube

As far as configuration settings are concerned, you can keep the cube in pristine condition or show it as worn, and instruct the gadget to keep the mirrors visible even when it's not the active application.
The other options are shared between most Yahoo! Widget Engine gadgets: you can make the frame stay on top or below any other windows, set the tool to ignore the mouse cursor and prevent dragging, as well as adjust the frame's opacity level.

Conclusion

To sum it up, this is a simple and entertaining widget for playing with a Rubik's cube. However, you should keep in mind that it won't receive additional updates, since the Yahoo! Widget Engine project was discontinued a while back.
