here's a fun little app i cooked up yesterday -- an ASCII mandelbrot browser written as a mod_parrot handler. it's pretty speedy (assuming your connection isn't holding you back), and it's the first handler i've written that parses form inputs.
for now, it's on my mod_parrot page at http://www.smashing.org/mod_parrot, which links to a separate web server just in case mod_parrot blows up. :) is it useful? not really. does it help you waste 5 minutes of your day? certainly. :) -jeff
