A note about Javascript.

The gallery makes some use of Javascript when image interaction or animation is required. Thus if you have Javascript turned off in your browser, you may be unable to interact or trigger animation. Please turn on Javascript if you wish to experience the illusion gallery in full.

Note that Javascript is also known as Jscript, ECMAscript and Inscript, your web browser preferences may refer to it by these names.
