Be Creative - Have a Black Smoke machine. Sprinkle your guests with a cloudburst of water at sudden, unexpected times. Have some pre-recorded whispers come from your speakers throughout the night. Play some Lost-inspired music. If you have a friend named Charlie attending your party, annoy the heck out of him by repeatedly saying in your best Desmond impersonation, "You're gonna die, brother."
Have fun. Print out a picture of my face and post it near your television set so I can be there in spirit!
