This plugin that I made over a few days adds the ability for you to throw bricks at glass, or even mobs, and people that might have beef with you 
It automatically hooks into Lands and WorldGuard, allowing administrators and land owners to prevent people from messing their protected areas up with bricks.
WorldGuard stuff:
Check the bricks-can-break-glass flag on all relevant regions, by default as of now it is set to true, if not defined by the user.
Lands stuff:
Bricks don't break glass in a land claim, if the block-break flag is disabled in the relevant lands.
Config stuff:
Several values can be customised under ThrowableBricks/config.yml
damageFromBrick: Damage when an entity is hit by a brick.
powerDamageMultiplier: The damage multiplier to apply with the Power enchantment.
defaultPickupDelay: How long in ticks until the brick can be picked up again.
minTicksLived: How many ticks need to pass before the brick can hurt entities.
checkDistance: The distance to check for any available entities to damage.
cooldown: How long until a brick can the thrown again.
damageMultipleEntitiesAtOnce: If bricks should hit multiple entities at once.
allowEnchantmentsOnThrowableItem: If bricks can be enchanted with Power, or Punch.
throwMaterial: The item material to use for the brick, by default of course, it's BRICK.
throwSound: The sound to play when the brick is thrown.
smashSound: The sound to play when the brick shatters.
breakableMaterials: A list of materials that the brick will break if they're hit with it.
