It's pointless! It's JavaScript! It's Here!
I was playing around with the JavaScript for highlighting buttons with the onMouseOver command, and I discovered that I didn't have to update the image the mouse actually passed over. This lead me to think it would be fun to make a little puzzle out of it, and that's what you see before you.
Silver tiles are considered to be "On" and black tiles are considered to be "Off." Whenever the mouse pointer passes into a tile it will turn another tile on or off, and whenever the pointer leaves a tile it will perform the opposite action on a yet another tile. For example, passing into the tile in the upper left corner might switch on the one in the lower left, and leaving it might turn off the middle one. The challenge is to shut all of the tiles off(or switch them all on, if you prefer). Hint - you'll have to leave the mouse on the last tile for the whole puzzle to be one color.
There's nothing in the code to sound whistles and shoot off fireworks if you succeed - you just get the satisfaction of having completed the puzzle. Hey, what did you expect from a Pointless JavaScript Puzzle? Go nuts, and have fun. ...Oh, by the way, if you actually click on a tile the puzzle will reload, so be careful. If you're not 100% satisfied, check out the disclaimer haiku in the alt text.
