The ferris sweep is a small form factor, split, vertically staggered, matrix keyboard. These models contain a sleeve for the keyboard, tent for the sleeve, and case for the whole keyboard. You can use a rubber band to keep the case closed and hold down your cables. It is a low tech and practical solution and I use it to bring my keyboard to work.
