Flutterby™! : Gamebutton Arcade

The game that got me hooked on programming was "asteroid" on the KIM-1. With a 6 digit LED display this wasn't anywhere near even the vector graphics "Asteriods" you remember from the early video arcades, but dodging those blinking bars and then learning how to set up my own patterns and make them go faster or slower got me started down the tortuous road of 6502 machine language. And yes, there are still opcodes I remember. Anyway, Camworld had a link to the Gamebutton Arcade, games written in JavaScript played entirely within a button. And the top one is an asteriod dodging game. Took me right back to those days.
