I wrote this small applet twenty years ago, lost it to the sands of time – and found it again at http://www.1archive.com/java/fire/… (Thanks guys!)
If you have a half-decent browser, it will probably refuse to show the embedded applet in the fire.html page,
so use this command instead:
$ appletviewer https://javier.rodriguez.org.mx/java/fire/fire.html
The source code is available at https://javier.rodriguez.org.mx/java/fire/.
Happy 20th Birthday, Java!
