Here are some toys in Java.
(01/25/13) These are Java applets, meaning that they run in a Java virtual machine started by your web browser. In 2012 and 2013, multiple security holes have been found in this mechanism; attackers have exploited these holes to take over the operating systems of computers that execute malware applets. Some of these holes have been patched by Oracle, and some browsers and OS producers have deployed additional measures to disable Java applets. If you enable Java in your browser, be sure your virtual machine is up-to-date, and be careful which web sites you visit.
