ABOUT AMM LAB.
INTELLIGENT MEDIA TECHNOLOGY AND INDUSTRIAL CREATION CO.
Welcome to AMM Lab! This is my personal lab for browser tools, games and technical notes. If something here is useful or fun, keep it bookmarked or pass it along.
I make small tools, browser games and standalone games, and write about what I learn along the way.
