This is a QR code. A QR Code is a 2-dimensional barcode, which has encoded in it a URL (web address), text, or other information. It can be read by a QR code scanner, including QR scanner smartphone apps. Once you have an app installed on your smartphone, open the app and hold your phone’s camera over a QR code to read it. Most QR codes you’ll come across have a URL encoded, so chances are when you read the QR code it will take you to a web page.

The long download problem is now fixed (all
the supporting files are combined into one Jar

This applet allows you to graph and rotate 3D surfaces. The instructions of use
are clear but the page design could be better.

Technical Remarks:

Has explanations on the functions of each button. For some reason it takes a
long time to load the applet itself even when using a fast connection.
