I want my ashes ground fine and tossed into the air conditioning intakes of some library. That way they'll be dusting me for years to come, and I will continue to make trouble for libraries after I'm gone.

Alternately, I'd like to be done up in a plastic cylinder (like a starfish in a biology lab) and a large screw-eye set in the top. Buried vertically, folks could pull me up whenever they wanted to see how natural I as looking there I'd be -- naked, making an obscene gesture with both hands for eternity....
