All of the images, processing, and calculations shown in the IDL Demo are being performed LIVE by IDL. The IDL Demo may be started by typing "demo" at the IDL prompt: IDL> demo The IDL demo may also be started by typing "idldemo" at the UNIX prompt: $ idldemo Running the demo in this fashion, or by double-clicking on the "IDL Demo" icon on Macintosh or Windows platforms will bypass the license manager (so there will be no timeout of IDL). Once started, you may run the IDL Tour from the "Tour" menu, or other demos from the "Demo" menu.
