Farbrausch, one of the PC demoscene's leading groups, have released their tool Werkzeug to the public. Werkzeug is a tool to create stunning graphical demos, by including 3D effects, music, textures, 3D scenes and more.
Old demosceners, like myself, probably remember TRSI's demomaker on the Amiga back in the '80-ies but this is a complete different tool. Seeing is believing. After seeing it in action on Assembly 2001 (can be a year earlier/later), I knew my demosystem DemoGL was a joke compared to that system. 
Although the demoscene is not what it used to be, it's great that legends like Chaos / Farbrausch release their tools to the public so people who always wondered how they were able to put minutes of 3D scenes, textures and multi-channel, full stereo music in 64KB can now see how it was done.
If you can't get enough of these great demo shows, you can turn to http://www.scene.org for more downloads, or even internet TV: Yodel broadcasts 24/7 demos from then and now at: http://62.65.8.228:8000/;stream.nsv (winamp)
