UpsideDown

Getting fed up of people building annoying structures, or running around PvP'ing everyone with their sneaky griefing clients?
The best way to prevent that is to turn their screens upside-down by inverting their FOV.
Simply type /udown [player] and their screen will get magically reverted! You can also do it for a certain time, for example, /udown [player] 15m or /udown [player] 30s.
to undo, /uudown [player] and their screen will get magically restored.
Feeling sadistic or maybe you just want to have some fun? Turn everyone on your server's screen upsidedown, with the command /udownall (time accepted as second argument), undo with /uudownall.

Comes with permissions, as standard:
upsidedown.udown: allows /udown.
upsidedown.uudown: allows /uudown.
upsidedown.udownall: allows /udownall.
upsidedown.uudownall: allows /uudownall.

You're probably wondering how this works? Well, by setting a player with a slowness potion with a high strength, you can mess up their FOV, movements and much more! Trust me, its absolutely hilarious. Great for taking whole server photos, simply get all your players to one place, then type /udownall to stop them running away :D.
Source code coming soon!

K4G made this awesome video showing how to use UpsideDown. It'd be awesome if you subscribed, or liked, or favourited to show your appreciation :)
