What special effects you can do with unclosed sectors?

Doomwiki says that unclosed sectors can be used for special effects. Anyone haves examples of what can you do with these?

I don't work much with unclosed sectors, but one use which come to mind is to set the speed of a BOOM conveyor.

You can also use it to make light look like it's reflecting off of water or glass. Vex-Zdaemon.wad does this on Map07 in the water sectors. OGL breaks the effect though.

How so?

You make a linedef in the mid of the space, then you add a special for setting the speed and direction of a conveyor belt (various, one of these is the special 253)

OK. I always just use one of the sides of a sector when I need a control linedef. But I can see how the other would work, too.

Its good to use this technique, but i like put linedefs outer the playing part of the map, is like putting control sectors, and i can find them more easily

Very cool effect! I tried to do it and in some cases is very easy to do!

And the best is that works in vanilla!
