I came across a picture somewhere on the internet a while back that had unique Pokéball ideas but were clearly jokes (e.g. Extra Ball - allows you to hold 7 Pokémon). However I thought some new Pokéball ideas could come in handy so I thought I'd share them with you all! Most of these are unique. All statistics and numbers are changeable, they're just examples:

1. Color Ball:
This is one I found on the picture but added details, once captured it has a percentage chance (e.g. 20%) of making the Pokémon Shiny, but has a very low Catch Rate (CR) 0.5x.

2. InvisiBall:
Another from the picture but slightly edited. The InvisiBall has a higher CR on evasive Pokémon (i.e. Abra) and can also be used in the Safari Zone, CR of 4x-6x. (There's a list here of Pokémon that Escape but I'm not sure  how it'll work in PU: http://bulbapedia.bulbagarden.net/wiki/Escape). However, the InvisiBall doesn't work when moves and abilities such as Arena Trap and Mean Look are in play - falls to 1x.

3. UniBall:
Has an extremely high CR (8x-16x) but the Pokémon is automatically released once fainted. Would generally be used by breeders who wouldn't want to fight with the Pokémon.

4. Thunder Ball:
This Pokéball is one I'm not sure of, it could be pointless. It has a higher CR than an Ultra Ball (4x-6x) but the Pokémon caught is permanently Paralyzed. This is controversial as it stops the Pokémon from being able to go under other stat changes.

5. Expert Ball:
The CR increases the more Pokémon the trainer has caught:
1-10 Pokémon: 1x
11-20 Pokémon: 3x
21-30 Pokémon: 4.5x
31-50 Pokémon: 8x

6. Sweet Ball:
Has a higher CR of 3x if the Pokémon was found using Sweet Scent.

7. Thief Ball:
Another one I found on the picture but edited a lot (original text: high CR but Pokémon will hate you forever). My version is: Very high catch rate (6x-8x) but caught Pokémon will have 0 happiness and won't listen to the player from time to time (say 25%). The rate of ignoring will fall the higher the happiness goes.

8. Guild/Buddy Ball:
Another concept I'm not so sure about but I added it in for the Guilds and in case a Buddy system is/will be implemented into PU. If a member of your Guild or Buddy List has the Pokémon then the CR will increase to 2x-3x (1x if not).

9. Dual Ball:
Can be used twice but only to catch the same Pokémon (i.e. 2 Abra's). The second throw has a triple catch rate (3x). Again good for breeders.

10. Trade ball:
If you have 6 Pokémon in your party and you catch one, the Trade Ball will allow you to switch one of the Pokémon currently in your party with the Pokémon you just caught, sending the traded one to the PC instead.

These are all the ideas I have so far! Please let me know what you think! And if the PU Team wants I could try to make these Icons (I have a basic idea on how these can look) but I'm not the greatest pixel artist.

I looked through the In-Forum Games and didn't see this one here, so I thought I'd  start it up. I put this up somewhere a while ago and it did really well.
The name's probably a bit confusing, so here's what you do, the first person starts off by saying something about themselves, (i.e. < My favourite Pokemon is Mew) then asks the next person that's going to reply, something about the previous bit (i.e. Also has a legendary Pokemon as a favourite?)
The person replying then answers that question (i.e. ^No, my favourite Pokemon is Growlith) and it starts all over again, Here's an example:

John:
< Loves playing the Wii
V Owns a Wii?

(Two  days later)Alice:
^ No, PS3 all the way!
< Wants a pet cat
V Likes cats?

Easy huh? Okay, so I'm gonna start...
< Just joined the PU forums
V Is also new to the PU forums?
