It's a pity because many games and educational demos were made with java applets. What will happen to the sites still active which contain applets? Like this one: http://www.clickmazes.com/_applets.htm
Is there a way to run applets in a safe way? Dunno, some web browser with an emulator plugin? Maybe a retrobrowser within a virtual machine? Any recommendations?

Camera sunglasses make me think of virtual reality. Who knows if it could be possible to provoke sleep state simulations with virtual reality goggles.

I was googling something like: sounds australia birds preview
And found this blog with sounds to give paintings a sort of soundtrack:

The blogroll links on the right seems also to be worth exploring for more sounds.
I guess the strategy here would be to associate sounds to images so that when your semi-awake listens into sounds your dream be brought someway to the corresponding scenery / painting / video. Makes sense?
