Based upon discussion, and results from the poll - there will be 2 prisoners in each cell.  The punishment of Solitary Confinement will also be available.  I've posted a cell picture (just use your imagination to change the colors and make the door high-tech).  Cells in solitary would have solid doors, no furniture, and a choice of either very bright light, or complete darkness.  The cells in solitary can be individually temperature controlled (bwahahaha).
