I don't have much yet, but every beginning is one:
Monster Classes
The Sirine, a fully approved part of Oslecamo's Improved Monster Classes.
Prestige Classes
Tombsinger, a necromantic bard
Corpsesculpter, a necromantic prestige class that gets a bit more creative with the raw materials.
Feats
Epic Landlord, an epic progression for the Landlord feat.
