A scenario that showcases all of the simple visual effects that can be created without mods. It has a simple walkthrough format, showing you each item and giving a basic description of how it is produced.
This contains every effect I have seen in other scenarios of the same kind except for the flashing lights effect. (Which, by the way, really isn't useful in a scenario.)
This could (and let me stress the word could) be very useful for people with basic knowledge of the scenario editor who want to extend themselves.
