A flimsy lil thing for animating a series of ascii characters on an html page.
<div id='one'></div>
<script type="text/javascript" src="lib/ascii-animator.js"></script>
<script type="text/javascript">
frames = ['▁', '▃', '▄', '▅', '▆', '▇'];
new AsciiAnimator('one', frames, 120, 'right', false).run();
</script>
See index.html for more inspiration. Or go it alone :-)
