It wasn't running fast enough on my computer because he used the swirl effect to make a spiral. This one just uses rotation and a spiral made in MS Paint. Stare at the center of the spinning spiral for about 30 seconds, then look at something else. I suggest setting speed to around 30 or -30. Positive numbers make the spiral "shrink" (causing other things to appear to grow). Negative numbers vise-versa. http://scratch.mit.edu/static/projects/Chupi/20967_sm.png http://scratch.mit.edu/projects/Chupi/3526 Not yet a playable game, but it demonstrates some basics for a Mario-style game: -Jump on enemies to squash them. -Being hit decrements the number of lives, then makes you invincible for a second or two so you don't lose more lives from one hit. -Touching an enemy from above kills it; touching one from the side or from below kills you. TO DO: -Add more enemies. Just clone the mouse a few times. -More kinds of enemies. A bat or bee, maybe. -Add platforms. Just draw them on the stage in that dark gray color the floor is. -Probably needs some work to bounce off the bottom of platforms or jump through them sanely. -Start with fewer lives? 9 is traditional for a cat, but seems to make a fairly lame game. http://scratch.mit.edu/static/projects/Chupi/3526_sm.png http://scratch.mit.edu/projects/Chupi/3340 USE: Set the pixel size and maximum iteration count with the sliders, and hit the green flag go. -Big pixels make the picture blockier, but doubling the pixel size quadruples speed. -Fewer iterations give less detail toward the inside and (because of the color scaling) make more abrupt color changes. More iterations make a better picture but take much longer. HOW IT WORKS: -Image drawing: It draws rows of pixels by moving forward one brush-width with the pen down, then changing the color. After each row, it picks up the pen and returns to the start of the next row, one brush-width down. This takes two nested repeats. -Fractal: For each point, it initializes the complex numbers C and Z to the current point. It then repeatedly applies Z=Z^2+C until Z escapes from a circle of radius 2. Iteration count gives pixel color. This is the innermost repeat-until. http://scratch.mit.edu/static/projects/Chupi/3340_sm.png
