At the port just East of spawn, there is a small fountain and a sign that encourages you to throw your offerings to the Crafty Gods into it. Instead of it being a simple set piece, why don't you give it some purpose?
You could put a tonne of hoppers at the bottom, and at the end of every month, you could give a completely random person on the server all of the stuff that was thrown into there, like a poor-man's lottery of sorts! You could probably incorporate a sorting system that stops utter garbage from being given away (eg, dirt, gravel, flowers, etc.)
But that's just my two cents...
