A big part of the demo scene were intros, not only crack intros that were displayed before the actual game as some form of credit and advertisement for a group's bulletin boards, but also intros that were released on their own or as part of disks. Yes, trading back then was not limited to games and apps, but also pure demo-scene productions.
All available intros are listed on the main page from where you can make your selection. It would have been nice if the original groups were listed on the page. Intros start to play right after you have clicked on one .
You can't change the volume of audio on the page or pause an intro which is definitely something that the operators of the page should consider adding to it to make it a more comfortable experience. It is a trip down nostalgia lane for those of use who experienced the scene back then first hand, and an opportunity for people who missed it all to get a glimpse. Then again, it is likely that the majority will be shocked by the audio-visual quality.
