I find this charming

marrael makes up names for non-existent rocks:

Klodstite: The crystal that helps you lose weight.
Goflykite: The crystal that tells other people to buzz off.
Traphiklite: The crystal you carry for safe travels.
Holmetite: The crystal for safety and security.
Isntrite: The crystal useful for proofreaders and fact checkers. Caution: Makes all minor errors jump out at you. ;)

Can be followed at #madeupcrystals on twitter if you do that sort of thing.
