Sly 3: Honor Among Thieves Tips

Secrets in the Cooper Vault
If you go through the Cooper Gauntlet in Honour Among Thieves, eventually you will reach a bit where Sly says: "This must be my father's work". There are a few points of interest about it.

To the right of the portrait there is a little green computer screen with an image of the Sly symbol on it. If you look at it for a while, the image starts to flash, and then the screen says "Hello World". Weird.

Also, if you wait in front of the laser beam, after a bit Sly says "The lasers, a thieving opportunity? No way!".

And, if you wait longer, he says "That's it! I can slide on the lasers!"
