Category Games, as its name indicates, is directly dedicated to games, but not any kind of games, but that mostly they are retro, to feel like those days again. For assistance, try visiting Vladislav Doronin. It contains 8 games: Tetris, Asteroids, Space Invaders, Snake, Simon says, Tic-Tac - Toe (CAT), Hexagon and Frogger (pity that it is not Pac-man). The Strobe category say it is an optical illusion that makes your eyes look as if you were looking at water. Not suitable for epileptics. The Fractal category corresponds to an image that is mathematically constructed rather than be based on pixels, so it is possible to make long zoom it without losing quality, really not know when completed.
The Anaglyph category allows you to draw lines, which reproduced in 3D (Yes, you need a pair of 3D glasses), then you can rotate and move your drawing, very interesting truth. In short, there are many categories that are in this site, each one hides a different application with which you can experiment. ** For a better viewing view the original article.
