New index page: Simulations/games

I've written a new topic index page for my site: Games, simulations, and animations. Except for the note about Tile Game, everything on it is something I've already published.

Condensed list of the contents: Tile Game, Fire Worms, Mouse-maze, 15-puzzle, screen savers, Varychase, Linkage, Bouncyworm, Brownian Tree, pendulum animation.
