I've been learning Bukkit API for the last week, and have gotten far enough to publish my first plugin!

DL: http://dev.bukkit.org/bukkit-plugins/googler/
SRC: github.com/TheDigitalDev/GooglerPlugin

So, what have you guys created with Bukkit/Spigot API?

Update: Updated plugin to version 0.0.5, uploading updated source on github soon

I created many plugins but I didn't publish them
My plugins:
» Varo (not finished)
» BuildIt (not finished)
» A lobby plugin with shop, LuckChests etc.
» OwnerCommands
» BlockParty with Shop, money, highscores etc.
» FlappyBird (inventory game)
» InvClickGame (inventory game)
» Trains (This is like subway surfer)
» Little particle plugin

And the very best:
Clans
it contains:
» Don't hurt players in same clan
» Clan base
» clan info
» Clan owner
» Donate items to other clans, the clan owner of this clan can get them from an inventory
» Kick, invite, make player to clan owner
» Clan battles: Challenge other clans, they can decide if the want a battle, if yes, there is a snowball batlle with special items like . bows, etc. This is very nice!!!
» Clan list (lists clans)
