Old tubes are great for just about everything: attaching broken rear blinkies for example. I made a carnical mark with them once.
I always have many front lights whose handlebar attachment is broken around the house for general use.
frames are great to hang towels and other clothing items they work as coat hangers too. Rear matellic baskets work well as kitchen trash or in the bedroom to place socks and nuderwear.
I have been thinking of setting up an using an old bike and a dynamic front light as alternative source of lighting in case of nuclear disaster.
