Toggler mini-game from flooble.com

Flooble's Toggler is a free mini-game that is small enough to be placed into any page's sidebar. In fact, it's only 130 pixels wide! The game involves clicking buttons on a 4x4 grid, toggling them from [X] to [.]... Toggle them all and you win, but be careful - any time you toggle a button, the four around it get toggled as well. See how many moves it takes you. Put it into your sidebar to amuse your visitors.
