Virtual Escape by Equinox
The first production I've been running is called Virtual Escape, and is from a well known ST demo group called Equinox.

This demo focuses the most on 3D effects. Especially bouncing balls and other objects. Most of the effects either uses filled 3D vectors, or utilise the popular dot vector shapes. The most impressive being 11 balls bouncing around at the same time. There is a slight limitation to that screen though, as you notice the balls are not actually true 3D as you can't see anything through them or behind them so some tricks are being used to get 11 on screen at once.
Some other dot vector screens add some cool motion blur effects as well as object manipulation.
It is still a very good and impressive production. It also has a load of filled vector shapes zooming around the screen in certain scenes. The popular space ship shapes appearing quite a few times, and these are all smooth.
The 2D artwork used in the production is of a high standard too, as are the effects used to bring screens and transitions in, as well as some quite unique text entry and exit effects.
The music is a series of chip tunes that works well, but can get a bit annoying as the demo goes on. Still quite nice though.
Definitely worth a look, even if you can only run it via emulation.
