What do you keep under your bed?

For many years we had a screen door and tubs of CDs under our bed.  I like this better than those big cabinets that sit at the bottom of the bed where the TV levitates straight up.  This is more elegant, although I think someone built this for themselves and it’s not commercially available, it could use a little more refining.  It would be cool if it were on a sleep timer and could also wake you up in the morning.
