This popular free service allows you to easily create your own cool, eye-catching Java applets for your Web site. No knowledge of Java programming is required. The JunkMachine will generate HTML code that you can simply cut and paste onto your site. You can either use this applet at this site or download the necessary .class files and run the applet locally (which they recommend, due to the high traffic at this site). (This applet was formerly known as the JavaMachine, but had to undergo a name change for trademark reasons).
