If resources aren't a problem for you....place fence foundations down parallel to each other and very close to one another. Then place railings on them. Do this inside a 2x2x1 box. Make the walls window walls. Use a ramp on the side of one of the walls to drag him up and onto the rails. This will place him in constant free fall. This will cause him to need to be fed and watered every 18-72 hours depending on your server settings. Once again, if resources aren't an issue for you......place an omnidirectional light in two of the corners of that 2x2x1 box and turn them on. Then give him an awesome pair of sunglasses. The engram for sunglasses is called night vision goggles. He'll have a very white Christmas when he logs in. Dress him in hide armor unless you live in extreme weather.
