An unsorted collection of useless demos that I've made.
All of these are single-page HTML documents.
One-dimensional cellular automata.
Less of a gradient and more of an iteration of all the hex values between two colors.
Mandelbrot set explorer.
Unlike most, this one actually calculates the set in real time. Very slow and inefficient.
Supposed to look like one of those candlestick-or-two-faces optical illusions.
Uses a simple formula to create a pretty cool effect.
Pong clone. Created the collision algorithm myself.
Use A/Z to move the left paddle and K/M to move the right paddle. Press the W key to disable the left paddle (like playing against a [W]all), and the R key to [R]eset the ball's position if it gets stuck.
Based on an animation I saw in a Numberphile video.
Snake clone.
Incomplete tetris clone.
St. Petersburg Lottery Demonstration
2D cellular automata using a randomly-weighted perceptron as a kernel.
Demonstration of bilinear interpolation.
Animated demonstration of Perlin Noise.
