Gingerbread Man

This makes a Gingerbread man, by the equations newx=1-y + abs(x) y=x x=newx and repeating them.

Mersenne Primes!!!

This is a fast program to generate Mersenne Primes. The list "Mersenne Prime N" shows the prime n in the function 2^n -1, which is also prime, and the list "primes" simply shows the primes that have been checked. To make this MUCH faster, download it and run it using Turbo mode(shift-click on Extras, click 'set stepping speeed...' then click Turbo. And no, you probably won't find the 45th Mersenne prime,2^43102609 -1, using this program.

String Art 2

This simulates making string art along pegs on a circle in which you choose a point, choose another point which is (shape order) pegs from the first peg, make the string there, make a string back to the first peg+1, and repeat. Try shape order 309!

Feather Fractal v2

This program creates a "Feather Fractal", which is more of a strange attractor, as described in Clifford Pickover's "Mazes for the Mind". Changelog: v2: added color settings

Thank You!(To Scratch Team)

This is a thank you to the Scratch team for taking the time to see me when I came to the Media Lab, during a big road trip all over the U.S.

Chaos_Game_v3

This is a modified version of mres's version of Cyclone103's Chaos Game ((link to project)). In this version, you can: * Drag the corners of the triangle (red, blue, and green) * Control how far the pen moves on each step (with the SCALE slider) *And, it has been speeded up a lot (almost 8x) from the previous version! Try adjusting the slider and moving the corners, click the Green Flag, and observe how the pattern changes On each step, the pen randomly chooses one of the three corners, moves a certain percentage of the way towards that corner, and draws a dot. The SCALE slider controls the percentage. Lastly, download to make faster!

Autograph Machine

Instructions: Set "Type" to one of the following settings to choose the following mode: 0: Automatic 1: Manual If you choose Manual mode, you can change "PenChange", "Degrees", and "DegreesType" to make an autograph depending on those settings. If you choose Automatic mode, you can change PenChange, but otherwise, sit back and relax as you watch the autographs spin out before you! Note: you cannot change from one mode to another. You have to press the flag, set the new type, and press start.

Projectile Grapher

This is a real-time projectile grapher to, with almost any starting condition, graph the trajectory. To use: Set Velocity and Angle to any measurement you like, then press 'START' The time for the point's place will be shown, including the total distance the point will go. I suggest hacking into the code and changing it so that it will display a graph of all trajectories for a given angle, each time changing the velocity by one. This will give an old-fasioned gradient effect. The units can be any size you wish, even in miles!

Serpenski Triangle Maker

A Seirpenski Triangle is a fractal, i.e, it is infinitely detailed. It is also self-similar, by seeing the triangles in triangles in triangles in triangles in triangles... And so on. There are, mainly, three different techniques of making a Serpenski Triangle. The first technique involves taking three copies of any image, and assembling them to make a triangle with a hole. This image is then put through the process again. Repeat this infinitely to get the full Serpenski Triangle. The second technique is as follows: With a triangle, remove an upside-down triangle from the center. Then repeat the process with each of the other triangles, infinitely. The last technique uses randomness, and is as follows: Pich a random vertex of a triangle. Move halfway to it. Make a dot there. Repeat infinitely. I used the last method in this project, and I hope you like it! By the way, the dimension of this fractal is log3/log2, or about 1.58496. In other words, it's little more than halfway between a line and a plane. Lastly, the area of the triangle is 0.

Fractal Recursion#1

This is a "half-fractal" that I made blindly, coming up with this. Change MaxSize to change the maximun size for the lines. Otherwise, sit back and relax!

Factorial Calculator

This is a calculator I made to find factorials (symbolised by a!) using Scratch. Instructions: 1:set A to the input, and then press "Next". 2: That's it! Factorials are numbers created by multiplying a number (in this case, A) by (A-1) and then by (A-2), and so on until the multiplyer is 1.

Hailstone Sequence

This is a program I made to graph the "Hailstone Sequence" which is: If y is even, the next y=y/2 If y is odd, the next y=3y+1 To change the starting number, first press the flag, change StartNumber, and then press START. If the y of the pen is> 360, if the x of the pen is > 480, or if it repeats endlessly in the 4-2-1-4 pattern, the program will stop, and you will have to try again, pressing the flag first. To get to the far side, you will have to find a number that can go through 160 iterations, and be in the constraints above. PLEASE post your number and the x and y it got to in the "Comments" box.

Fast Lane Art

Change PenSpeed to alter how fast the sprite/pen goes, and alter Turnyness to alter the line's turn. Be sure absolutely NOT to press the M Key. Actually, I want you to, but if I tell you NOT to do something, you will do it. Right? Well, have fun anyway. This project was based on the other project WOAAHHH!!! by another user.
