If you are at all interested in the Eurodemos I suggest you check out this DVD. It's all about the demoscene.
One side is all old skool stuff from the early 90s to about 97, before 3D accelerators. Some of them you probably have to be aware of the limits to computer power, about what else was out there, about the state of video games at the time etc to appreciate what made them interesting at the time. Others are still just well done and interesting today.
It's cool though that there is an easy way to look at them. This stuff is before Windows back in the DOS age where you had to run QEMM and edit your config.sys and autoexec.bat files. Often you had to have certain graphic cards and many demos were written for specific sound cards. One of the most common requirements for a while as a GUS card (Gravis Ultrasound) mainly because at the time it was one of the only cards that could play multiple samples in hardware. I heard there is some work in the area of emluating those older machines just to run the old demos.
The other side of the DVD is all new demos from the last 2 years. If you are into techno and abstract images you'll probably get a kick out of it.
The coolest part I think though is there's a 20 minute documentary about the demoscene. They interview various famous guys from the scene and show some footage of the crazy demoparties they have mostly in Europe. According to them, this year as of August there had already been 40+ parties. The biggest I guess is still Assembly which has been going on now for over 10 years. 4000+ geeks descend on some big arena and have a great time raving, coding, making art & music and playing games. It looks like they are having lots of fun.
Check it out!
