Ikea do a decorative glass container that is perfect for WK
i usually always use sunlight to grow WK
all WK are ghetto :P
Go down to the river (listen to springsteen first of course) and bring a peice of wood to work on, some thread, scissors, planting tools ect. right by the water dig up a nice wet clump of soil and mold it with your hands into a sphere. go find some moss and stuff from around you and wrap it round the sides (use javamoss if you brought some) then bind the ball with the thread do it well and dont skimp on quality. now hunt up some nice small plants and some more mosses and scape the top half by planting them in with tweezers.
done! bring it home and put it in a container filled with water and sand.
