EMERGENCY LIVING SYSTEM FOR JANE AND RAIN (1998) All major boulevards in Los Angeles are lined with the most gorgeous stately architectural scale trees. The Emergency Living System (ELS) was designed in the event that me and my son became homeless. It is a portable system which converts any of the large ornamental landscape trees in Los Angeles into a safe, private, and luxurious home. It fold into a backpack, and has built-in features like windows, a desk, sleeping bag, and roof.
