There's not much I have to say about web design that you won't learn from the fine authors mentioned in the Site Notes section. But I do have some nifty javascript to share.
This Binary Matrix Animation presents a table initially containing all 0s. Clicking on the table toggles an animation state, where "blips" will travel at varying speeds through the table. The above link works in a black background. There's also one designed for a white background although its color scheme could still use some fine tuning. I haven't done extensive testing, but verified that they work in both IE6/Win and Mozilla 1.6/Win. Fortunately, everything is available in the source of those two pages and you are more than welcome to use and modify. Enjoy!
