Fibonacci

A small page where you can let the browser to compute the Fibonacci numbers.

Mandelbrot set drawing in the browser
Generate the famous Mandelbrot-set in the browser. You can zoom-in/out and navigate around the drawing using buttons or entering the necessary parameters. Note that using a bigger number as “number of iterations” results in more accurate computation of the fractal image but also slower drawing.
 
Minesweeper in the browser (mobile friendly)

Uses HTML5 canvas and javascript.
If you have problems with the double-click event on your browser: there is also a version where the selection mode (show_field or mark_as_mine) can be toggled via a button: click here for the simple-click-version.

Fractal growth

See how a random image can be created on a grid, letting small dots move in random direction starting from the edge of the screen, until they come next to another dot that are already sit on the grid. At the beginning, only one dot are placed on the center of the grid.

Such kind of fractal image generation is called “simulation of diffusion-limited aggregation” and the generated images are called “Brownian tree clusters“.

 
Function drawing

This is a function visualiser that can draw any function in a cartesian coordinate system, where the plotted values are a function of x.

Example: you simply type in “Math.sin(x/50)*50”, hit Enter and a nice sinus curve will be shown.

Prime number generator

On this page, the prime numbers within the given range will be generated, and the number of primes within the range are also visualized in a graph.

Scramble

Lead your spaceship in a cave and avoid collision with the walls.

The game utilizes 2D animated sprites, collision detection and WebAudio.

This game is an ongoing project, i.e. not finished yet!

 
Play Yahtzee (Poker Dice)

This tool helps at playing the Yahtzee (some kind of poker dice game), so that you don´t have to have real dices at your hand. This program generates random dice rolls and lets you keep some of the dices and roll again. 

Special Relativity – Twin Paradox

On this web page you can compute the time difference that is measured between a moving (as f.e. a spaceship) and a stationary system (Earth). This paradox is called time dilatation and is described in Einstein’s Special Relativity Theory. For the computation, the Lorentz-factor is used.

Catch the ball

Another HTML5 game, where your task is to catch the falling balls and avoid collision with the bombs. Don’t forget to turn on your loudspeakers!
I have made this game with my 10 years old son.
