These are stable demonstration of ideas or just code samples. These are survivors of the Labs and most everything should work quite well. Some items in this section have been (or will be) used in production systems.
Enter at your own risk. While nothing here can hurt your computer, you may see error messages. There may be half-baked ideas or quick and dirty code samples in here. Some of these poor items will never see the light of day. All the good stuff from the Labs makes it up to the Demos section.
All the left over stuff that a website is supposed to have.
