They are really not that impressive when compared to the stuff you can find at the 5k contest. However, I learned a much from these in trying them on different browsers and different operating systems and different machine processor speeds. I think these are a big part of how I am able to intuit how browsers will handle different amounts of scripting and complexity. I’m proud of them. For those which use PHP, I also provide the source code for each. So, check them out if you’d like.
