Text-only dot matrix LCD animation

  In Firefox 5.0, the animation ran very slowly, 1 fps , not exactly the result he was looking for. Not sure if that is a browser issue, or an implementation issue.

    Same here. On Chrome 13.0.782.112 it ran smoothly, so probably just a Firefox problem.

    Smooth on iPad 2 using iCab browser, though took sometimes 1 - 2 seconds for character change radio to be picked up.

  > opacity = (1 + wolfAni[currentFrame][i]) / 10; This could be pre-calculated. >if(opacity != matrix[i].style.opacity); matrix[i].style.opacity = opacity That semicolon after the 'if' means the next line will always be executed regardless of the value of the condition, so the if is useless there. -- In the same spirit, I love the AA-Project[1], especially their demo, BB[2].
