K1 Visa Wizard
https://www.k1visawizard.com/Conway's Game of Life
https://conways-game-of-life-app.netlify.app/The algorithm is a cellular automaton devised by the British mathematician John Horton Conway in 1970. It is a zero-player game, meaning that its evolution is determined by its initial state, requiring no further input.
One interacts with the "Game of Life" by creating an initial configuration and observing how it evolves over time. Being Turing-complete, it can simulate a universal constructor or any other Turing machine.
Pynenburg & Collins Architecture
https://www.pc-architects.co.nz/I gave new life to the home page, team page, and about pages, and implemented several full-width banners. I also created a new full-width layout that would not override other pages with a fixed width.
Finally, I implemented a relatively user-friendly method for controlling the state of every page, allowing it to transition from full-width to fixed-width.
