Well, it didn't immediately click because the Beethoven song he used to test the program is better known by its German name: "Für Elise" (well, that's what the book of piano pieces I used to have calls that tune). Trouble is, everyone's associations to the name 'Eliza' is the 'AI' program by Joseph Weizenbaum...
Qu'on me donne six lignes écrites de la main du plus honnête homme, j'y trouverai de quoi le faire pendre.
that's called van Eck phreaking and has been around for a while now. With a sophisticated enough antenna array you can get basically a screen dump from someone's CRT monitor. With even better equipment and the right processing you can monitor closed circuit signals just by listening to the EMR they give off when current in run through them. Radioshack has the parts to build a toy that can tap a telephone line without splicing wire or having access to cables or trunks.

Ah, but it _is_ working. It's not your monitor that is emitting the signal - it's the cable between your computer and the monitor. :-)
