A Thing is an interactive object for a Web page that is developed with an authoring tool called ThingMaker that is sold by the Parable Corporation. A Thing can be a simple game ("Bill Gates' European Vacation"...hit him with a pie), an image that emerges from the page as you pass the mouse over a certain spot, a beetle that you can dress up as SuperBeetle, or anything you want to invent. Typically, a Thing arrives on your page and changes as your mouse rollover it, and again when you click on it. Things are intended to be easy to create, using ThingMaker, but you can also add ready-made Things to your Web pages that you can copy from the Parable Web site or elsewhere. To actually see a Thing or two, you must first download the ThingViewer from Parable.
ThingViewer is an approximately 500 kilobyte ActiveX control (downloadable in about five minutes). The HTML code for the Thing identifies images and other files through an OBJECT tag embedded on the HTML page. After you've created a Thing, Parable's tools make it easy to copyright your Thing and share it with others.
