Keyhole Challenge

Prove your ability as a game developer by working around arbitrary rules - in
this case, a tiny screen.

Here are the basic rules:

* The game must be small in terms of stage-size. If you have standard-sized
icons for games on your site, make it that size. Anything up to 100x100 is fine.
Let's say 10,000 pixels max, 200 max along either axis.

* The game should be involving. Very basic games like bat-and-ball barely count.

* For inescapable flash-platform reasons, the game is allowed to call a pop-up
helper window with a larger swf. This should only perform subordinate actions -
the game must be entirely playable with the small screen alone.

* Browsers often have a zoom function. To fit the spirit of these rules, your
game should render your graphics to a bitmap of the target size, so the larger
scale has a pixellated or 'mosaic' effect.

* If you want, you can also have a version which runs the game in 'zoom mode'.
To fit the spec, your game should be pixellated at the larger sizes as described
above.

* The game can do what it likes to attract attention graphically, but shouldn't
start the game or make any noise until the player clicks on it.

This challenge is just for fun (or honour, if you will), so feel free to do what
you want in any case.
