Inspired by a recent Slow Mo Guys video, I wrote a simulation for the shown effect. I think it looks pretty neat…

By using the formula 
for a big number 𝑛, you can approximate the mathematical constant 𝑒.

In a recent c’t article [1] they showed a game regarding vector mathematics, velocities, accelerations and positions.
I could not resist and wrote this program to simulate the game.
The only thing this program cannot do is to check the barriers. That you have to check for yourself.
You have a start position (red), an end position (green) and some barriers (white).
Your job is it to steer your little dot (bright yellow) onto the end position.
To make it more difficult, you are not allowed to change the dot’s position directly, but rather you accelerate it on each step.
Your acceleration vector (turquoise) also is not allowed to be longer than 𝟣𝟢 (dim yellow bubble) and at the end point your dot must have a velocity of (𝟢, 𝟢).
The fewer moves you need, the better your steering abilities.

Tinkering around with vectors, I created this fancy program. By left-clicking you spawn a white circle at your current mouse position. This circle then will emit a specific quantity of red pixels (which is 𝑐 = 𝟤 𝜋 𝑟 with 𝑟 = 𝟧𝟢). Those red pixels then get pushed across the screen until they eventually die out.

This program uses vector mathematics and colors to create triangular gradient. By simply left-clicking you create three points which then will be filled in with color.

In an attempt to make drawing using a computer mouse easier, I created JDrawer. By pressing the left mouse button, you start or stop drawing. By simply moving your cursor the program then draws accordingly. The line’s colors are picked at random.

This program lets you watch grains of sand fall. The grains shift in color, according to the color algorithm assigned. You also can build bridges to change the sand’s falling behavior.

This filter swaps the red and blue color values. It results in a rather soft image.
The original image (can also be found on my Stacking Stones post).
RGB Swap (just swaps the red and blue color value, that is why the lake appears red).
