apologies if you already received it.

hi,

I came across this link through
this months Cryptogram.

http://oculislabs.com/Products/ChameleonP.htm
The
link reads....

"Oculis Labsb Chameleon System protects your monitor against
eavesdropping. With Chameleon running, you can read your screen normally, but
no one else can. Chameleon protects against the shoulder-surfing eavesdropper
as well as opponents using sophisticated TEMPESTbtype electronic
surveillance."


I am curious to know how it prevents TEMPEST?

Also, is not clear the idea of
you seeing something at one gazepoint and some other thing at another
gazepoint.

Any insight is welcome.

Thank you,
