Mini-projects

I like making little playgrounds for testing out specific APIs or implementing small ideas. I often make useful components with quite good user experience using pure HTML, CSS, and JavaScript.

• NewtonsCradle - a visualization of Newton's Cradle for my physics project

Games

• snake-pygame - a good old snake game. Made with PyGame

• teplovs/lexer - JavaScript library for tokenizing with regular expressions
• animated-keyboard-shortcuts - add animation to keyboard shortcut hints (when user presses corresponding keys on a keyboard, keys on the screen get animated)

Machine learning

• sleep-patterns - analyzing sleep data and trying to predict good sleep patterns

Miscellaneous
